6-20 The final exam grades are on powerschool, and your quarter grade is complete with 1 missed homework dropped. Many of you have shown such growth this year as young adults, I know you'll be even more successful next year. If I don't see you tomorrow, have a safe and happy summer!
6-7 A few more examples from chapter 9, then an interactive web site on Trigonometry. We are remembering the appropriate sides to use in the Sin, Cos, and Tan ratios, now we need to use them to solve triangles. Handed out the review packet for the final. There will be some class time to work on it, but get the sooner you get started, the more of your specific questions can be addressed.
Assignment: the 12-7 worksheet: finish the front: 1-11, and on the back: 19-21. This will be due Friday in case you are doing the 9.1-9.3 packet before the quiz, however the packet will be accepted up until Friday also
6-3 Reviewing the 9.1-9.3 packet so we know what problems will be on the quiz, which is moved to Wednesday. Remember, completing that packet makes up for 2 missed homework assignments. Then a little more on Trig.
Assignment: On the back of our preprinted notes, complete #10-12. On the 12-7 worksheet, #1-3.
6-1 notes on solving proportions, that part of 9-5 is the last of chapter 9 that we will do. Quiz on Monday on 9.1-9.3, use the packet to review. Then we started some right-triangle trigonometry.
Assignment: pg. 471: 24-32 even.
5-27 Test today, then time to start homework.
Assignment: read pg. 450, on pg. 454: 2-20 even (for 14, 16, 18, and 20. factor after you combine the numerators so that maybe you can cancel a factor top and bottom.)
5-25 Test on Chapter 8 is Thursday, so quizzes back today. The only concept not on the quizzes that will be on the test is from 8.5, where we took each of the factors we found and set them equal to zero to find 2 x-values that will make the equation true.
We also used a middle-school skill, finding the LCM of 2 expressions, but now we can do it with variables and their exponents, and with binomial factors. Binomial factors are the kind we found in Chapter 8, 2 terms inside a parentheses.
Assignment: pg. 448: 2-14 even, and the chapter 8 review sheet: 1-13.
5-21 Reviewing factoring to solve, then notes on factoring to simplify rational expressions.
Assignment: pg. 441: 6-12 even, 18-26 even. I meant to assign 32, 34, 36, 46 and 48, so they will be added to Tuesday's assignment, do them ahead if you want.
5-19 Review before the quiz. After the quiz, a few notes on simplifying rational expressions from 9.1.
Assignment: Chap. 8 review pg. 429: 3-7, 10-12, 19, 34, 36, 38, 40, factor and solve: 46, 50, 52.
Alert: Quiz on Wednesday 5-19 on section 8.3-8.4
5-17 (for the record) Time in small groups to factor when a>1, that is, when you have to work around factors of the first coefficient as well as the constant. Then, notes on factoring a quadratic in order to solve it from section 8.5.
Assignment: If you were not a group leader, then you have an assignment to show your new mastery of factoring: 9-6 worksheet: 19-34. Everyone has pg. 417: 4-32 even, watch for problems where taking out a GCF will help you, and watch for those that match the special patterns.
5-13 entry slip on factoring, then section 8.4: factoring special trinomials. If you are still struggling with factoring, you should be getting some one on one extra help.
Assignment: pg. 411: 3-14, practice 9-7 worksheet: 3-5, 9, 10, 19, 42, 44, 47-49. Also, can still get credit for pg. 404 factoring from last class.
5-11 (for the record) reviewing for the quiz, followed by examples of factoring a trinomial when the coefficient of the first term isn't just 1.
Assignment: pg. 404-405: 2-40 even
5-7 Alert! Quiz on Tuesday on 8.1-8.2: factoring out a GCF, factoring a trinomial in to binomials, or both. We also learned how to find the binomials when the trinomial is a little more difficult.
Assignment: KUTA worksheet "when a>1": 1-26, omit 16, and notice on 8, 9, and 18, factoring out a GCF will help. Also: pg. 397: 86-100 even.
5-5 (for the record) We reviewed before the test and after the test we had a chance to practice factoring some more.
Assignment: Worksheet Practice 9-5: 1-33
Test Wednesday 7.1-7.5
5-3 Very difficult to go over the material for the test due to the heat. Notes on how to factor out a GCF if possible to make factoring a trinomial easier.
Assignment: Finish the a=1 worksheet, all the numbers we didn't do. Look out for #16. In the book: pg. 396-397: 30-40 even, 60-72 even.
4-29 We went over the review sheet before the quiz. Then we did more examples of factoring.
Assignment: "Factoring trinomials (a=1)" worksheet: 1-14, 18,19,23-25, on #8 check the negative factors of 24 and see why it is not factorable.
4-27: There seems to be some confusion about doing the chapter review assignment in addition to what was handed in during class Friday, so you may still do that assignment for credit. We reviewed for the quiz on 7.4 and 7.5 next class and then started on factoring. Instead of FOILing 2 binomials into a trinomial, we start with a trinomial and find the 2 binomials that are its factors.
Assignment: Finish the 7.4-7.5 review sheet; and pg. 396: 1-6 all, 8-28 even.
4-23 With a substitute: There will be a quiz on 7.4 and 7.5 Thursday 4-29. In class working on the Chapter 7 practice test worksheet #1-30 except 10 and 25 for a classwork grade.
Assignment: Chapter review pg. 379: 1-57 odd, skip 11 and 33.
4-21 Time after the quiz to practice dividing a polynomial by a monomial. finishing that assignment for homework. Then we started Chapter 8 with factoring out a GCF. (We think of it as un-distributing)
Assignment: finish pg. 372: 15-27 odd, pg. 389-390:4-16 even, 22-48 even.
There will be a quiz Wednesday 4-21 on section 7.3: multiplying 1 term by 2 or 3 terms, multiplying 2 terms by 2 terms (FOIL), multiplying 2 terms by 3 terms, and using these skills to find expressions for the area of a polygon.
4-19 Spent some time reviewing exponent skills from section 7.4, which are pretty rusty after the break. Try again on the Practice 8.3 worksheet if you had trouble, we all need the practice.
Briefly went over multiplying and dividing while in scientific notation, seemed to go well, some practice on that tonight.
You should have notes on doing division of multiple terms (called a polynomial) by 1 term (called a monomial) so that you can practice on pg. 372-3. If your notes aren't helping, try following example 1 and 2 on pg. 370. The first set of problems are review for the quiz on Wednesday, and should feel easy compared to the multiplying we did in class today.
Assignment: review for the quiz: pg. 356-358:7,27,33,41,73,93,97,113; scientific notation: pg. 368:110-116 even; dividing a polynomial by a monomial: pg. 372-373: 2-26 even.
4-8 Reviewing how to simplify multiplication and division with exponents even if we start out or end up with a negative exponent. Moving on to a use of negative exponents: scientific notation.
Assignment from 4-8 due 4-19: Worksheet 8.3: 1-33 odd(I apologize, the assignment you wrote down in class is longer, but I couldn't find it. 1-8, 9-15 odd, 17-22, 25-33. You may do 1-33 odd instead, but look at the others to make sure you're getting enough practice.) Other side 8.4: 1-18 all (the assignment on the board was 1-27 odd, but we didn't get to operations with scientific notation, so 1-18 all is better.) Some students had trouble with pg. 366-7: 38-78 even, so use your notes and/or book examples and try again if you need to.
4-6 If we are dividing 2 terms which have the same base, we can subtract exponents. Subtraction sometimes results in a negative number, so there is such a thing as a negative exponent. It can seem a little complicated to simplify these problems, just take 1 variable at a time. See example 3 on pg. 363 for help.
Assignment from 4-6 due 4-8: pg. 366-367: 38-78 even.
____________________________________________________________________
4-1 When we were multiplying 2 terms, we could simplify by adding the exponents of the matching variables. When we divide, we subtract. There's a good example of how this works in the middle of pg. 361.
Assignment: pg. 366: 2-8, 12-36 even.
3-30 Quiz today on 7.1 and 7.2 seemed to go well. Then on to multiplying special binomials: the sum and difference of 2 terms and squaring a binomial.
Assignment: pg. 357: 78 to 108 even.
3-26 (for the record) Quiz next class on 7.1 and 7.2: combining polynomials and simplifying exponential expressions.
We've multiplied 1 term by a parentheses with several terms inside and correctly applied the distributive property. Now we need to multiply 2 parentheses with 2 or more terms in each one. The distributive needs to be used so that each term in 1 parentheses multiplies each term in the other parentheses once. When we do that with 2 binomials, we call it the FOIL method.
Assignment: pg. 356-357: 32-46 even, 50-74 even.
3-24 (for the record) Simplifying exponential expressions and powers, even with the distributive.
Assignment: pg. 350:38-74 even, pg. 356: 2-24 even.
3-22 Test today on Chap. 6
Assignment: read pg. 347. Do pg. 349-350: #8-36 even.
3-18 (for the record) reviewing solving systems and going ahead with combining poynomials from chapter 7
Assignment: If you didn't finish in class, complete both sides of the worksheet adding and subtracting polynomials.
3-16 We reviewed before taking the quiz so we held off on much new material from chapter 7. We are done with chapter 6 and the test will be Monday. That's to give absentees a chance to make up the quiz and anyone who wants to get extra help after school Thursday or Friday.
No new assignment for today, some of you who were out or had excuses owe make-up work by Friday.
3-12 We looked at how graphing, substitution, and addition give us the same solution to a system. But each of these is a multi-step problem. Please use your notes of the examples we did. Your book also has clearly worked examples in sections 6.2 and 6.3. Our quiz next class is on the addition method. If you had trouble with the farmer worksheet, please get some help.
Assignment: Chapter 6 test form C worksheet front and back. ALERT!!! The first #10 on the back has fractions for the solution. You only need to find the first variable, you don't need to back-substitute to find the other variable.
3-10 It turns out that the addition method has a few more steps if neither of the variables drops out easily. If we want the coefficients of x or y to be opposites of each other, it might inolve finding a least common multiple, and multiplying BOTH equations so that one is the positive of the LCM and the other is the negative.
The most common example is 6 being the LCM of 2 and 3. So if you have 2x in one equation, you multiply that one by 3. If you have 3x in the other equation, you multiply that one by 2. But you also have to make 1 of them negative in order to cancel, so you're actually going to multiply by negative 2 instead of 2.
Don't forget to multiply each term on both sides. Then you're finally ready to add the equations together and solve for the variable that didn't drop out.
Assignment: The joke worksheet on addition. You will have to multiply one or both equations before you can add.
3-8 What if the coefficients aren't quiiiiite opposites of each other? That's ok, multiply both sides of one of the equations to make it the opposite you want. Use your notes or the example in the book at the top of page 315.
Quiz Wednesday on section 6.2 solving by substitution. You need 3 things: be able to solve one of the equations in the system for one of the variables, x or y. be able to solve the system by substituting the expresssion you found for the variable in the other equation. and know what it means when your variables drop out and you get a statement such as 3=-7 or 3=3.
Assignment: on the 6.3 worksheet: 3, 11-15. In the book: pg. 312-313: 14,16,18,44, and pg. 318: 6-12 even. AND study for the quiz. Help is available today and tomorrow after school.
3-4 Now we find out that if both equations are in standard form, we could try adding them together. IF the coefficients of one of the variables are opposites of each other, then that variable will drop out. Then we can solve for the other one and solve the system. You should be able to do these from your class examples, but if you lost them or you need another example, see pg. 314.
Assignment: 6.3 practice worksheet: 1-9, omit #3.
2-26 How do you solve a system algebraically if both equations are in standard form? Solve 1 of them for 1 of the variables. (go ahead and pick the easier one!) Then proceed with substitution to get values for x and y. What if your variables drop out while you're solving? Then the system is dependent or inconsistent. See your notes or examples in section 6.2 for help. Students seemed to be getting this and will get better with practice.
Assignment: pg. 312-313: 20, 22, 26, 32-42 even.
2-24 We graphed two more systems together and took the quiz on 6.1. Also 2 examples of solving by substitution. The homework problems have one equation of the system already solved for x or y, so they're just like what we did in class. If it would help to see another example worked out, see pg. 309 of your book.
Assignment: pg. 312: 1-12.
2-22 Sub today, so working independently on graphing to solve systems. (Concepts on which we spent the entire class 2-11, you should have notes) The quiz on Wednesday on section 6.1 will include checking solutions by substitution, identifying a solution from a graph, knowing the 3 types of systems by their graphs, and solving a system by graphing. Hopefully you used your classtime wisely.
Assignment: Pg. 305-306 #3-15 odd show substitution, 27, 29, 30. And study for the quiz.
2-11 Reviewing graphing from slope-intercept and standard form so that we can solve systems of linear equations by graphing to find the intersection.Quiz on section 6.1 on Wednesday 2-24.
Assignment: homework from 2-9 if not completed(pg. 305-307; 4-16 even, 25, 26, 32): read pg. 303-304, pg. 306: 18-24, 24-44 even,CORRECTION: 34-44 even.
2-5 Questions on the review sheet. Reviewed graphing a line from slope and y-intercepts. Learning to graph from both intercepts. Because our next step is to graph a system of 2 linear equations and find the point of intersection. If you ran out of time on the quiz, you should come after school by Monday as we will go over the quiz before the test, and you want to be in class. Also, if I can help you firm up your equation-writing skills, you should also come Monday.
Assignment: pg. 305-307: 4-16 even, 25, 26, 32 and study for the test!
2-3 (for the record) reviewed for the quiz, took the quiz, time on the review sheet for the test on Tuesday.
Assignment: Finish the chapter 5 test C front and back.
2-1 The quiz next class on 5.4 is on writing the equation of a line from given information, whether it's the slope and intercept, a graph, or just 2 points. The test on Chapter 5 will be Tuesday.
Assignment: finish the review worksheet on 5.4, front and back.
1-28 We reviewed for our quiz next class on slope: finding m in the equation, counting off of a graph, using the formula for 2 points, and using the formula for slope as a rate of change of 2 units. We also learned how to use the graph of a line to show an inequality instead of an equation.
Assignment: pg. 281-82: #2-14 check the section if you need to review how to graph inequalities, pg. 258: 3-11 odd, the directions say to find the slope, you also need to find b and write the equation of the line.
1-26 Assignment: pg. 273-275:2-4, 10-34 even, 36-46 even, remember to graph by plotting the y-intercept and counting the slope right on the graph.
1/22 Learning to write linear equations from 2 clues: slope and intercept, slope and point, or 2 points.
Assignment: Finish pg. 264 #1-14 if you haven't already. Writing equations worksheet both sides.
1-8 As I told you on Wednesday, we are having our last quiz on Tueday on Section 5.1-5.3, which would include slope. In order to make the quiz shorter and have more time for midterm review, the quiz will only cover 5.1 and 5.2.:
1)Substituting values for x and y into an equation to see if they are solutions
2)plotting points on the coordinate plane (x,y)
3)graphing linear equations by making a table of 3 values
4)rewriting linear equations from standard to slope-intercept form by solving for y.
If that last one was hard for you, please review the examples in section 5.2 on pg. 241 and 242.
Assignment: Study, study, study! Most of you got more than 1/2 of the review packet done in class, that was our last homework grade. Some of you are finishing the grahing packet because you had trouble solving for y. All late homework for credit, and make-up quizzes and tests were to be completed by today, a few of you have already come after school and made arrangements for additional time on Monday.
1-6 Notes today on slope of a linear equation: counting off of a graph, and using 2 points in the formula.
Assignment: pg. 257-259: 2-16 even, 28-34 even. It's printed at the bottom of the 3rd page of the notes.
Belated: 1-4: from 5.2: graphing a linear equation by making a table of values and plotting the points. Graphing a linear equation in standard form by first solving for y to rewrite it in slope-intercept form.
Assignment: pg. 246: 24-38 even, pg. 248: 58, 60, 66-76 even. All of those are listed on the packet with graphs you received.
12-22 As I mentioned in class, I was concerned that not knowing the impact your missed homework would have on your grade might cause you to ignore the problem for longer than you should. Because of my delay this quarter, I will accept late homework up to Jan. 8th on assignments up to Dec. 16th. You should be able to get all the information you need from the portal.
Today, review of skills on graphing coordinates and evaluating linear equations.
Some students need to finish their Chap. 3 test. We have been solving equations all this time, but you could also study inequalities and lever problems.
Assignment: pg. 232-236: 12, 14 (find the vocabulary words in the section), and 25 and 28 for which you need to show work. Pg. 246: 6-22 even.
Test on Chap. 4 (4.1,4.2,4.2,4.5,4.7) On Friday

Assignment: pg. 215: #1-4, 17, 22, 25-28, 32, and completing the 4.5 and 4.7 assignment if not already done.
12-4 Students worked with the sub today to fill in their copies of guided notes on the types of problems in sections 4.5 and 4.7. (we are skipping 4.4, 4.6 and 4.7, so that's it for this chapter!)
Assignment: written on the bottom of each page of the notes: pg. 185-187: #2-16 eve. Pg. 200-201: #2-8 even, and 12.
12-2 Today we reviewed lots of geometry facts and formulas that allow us to write useful equations to solve geometry problems.
Assignment:(at the bottom of the back page of the worksheet.) pg. 170-175: 1, 2-40 even, 50, 56, 58, omit # 12, 18, 28, 30, 36.
11-30 Moving on to section 4.2 with consecutive integer problems, and coin and stamp problems. Please be aware for the coin and stamp problems that using a table is considered part of the solution. I gave you blank tables on the worksheet for the homework, as you practice filling them in, try to remember so you'll be able to do your own to solve this type of problem.
Assignment: pg. 158-161 #4-16 even, and #22-36 even on the worksheet. See 11-23 for the assignment from last week that's also due Wed.
11-23 We are working on being able to translate verbal statements and word problems into equations. Please be aware for the word problems, you need to write and solve an algebraic equation (has a variable) even though you might be able to figure out the answer without the equation.
Assignment not due until Wed. 12-1--Have a nice turkey day--Pg. 151-4:#13-21 odd, 25, 26, 30, 33, 34, 38-40. Change as of 11-30: do #35 and 37 instead of 38-40.
11-19 Test, and translation of verbal expressions into algebraic equations to solve.
Assignment: pg. 151: #1-9 odd, 10-20 even
11-17 Test on Thursday on Chapter 3
Assignment: Practice test #1-20 (both sides) and in the book pg. 140-141 #5, 7-9, 13, 14, 38-40
11-13 We're finisihing up the chapter with 2-step inequalities, so, test next Thursday on Chap. 3
Assignment: Pg. 134 #98-126 even. Show solving steps but you don't need to graph the solution set.
Look below for the link to the website for practicing equation solving.
11-10 Quiz next class on 2-step equations and formula problems, including levers. We reviewed one-step inequalities and graphing the solutions. Remember: solve like an equation, but don't change to an equation, except--if you multiply or divide by a negative number, you must switch the inequality sign.
Assignment: Inequalities worksheet both sides: #9-16 and 1-16
11-6 Thorough review of 2-step equations, including like terms on one side, variables on both sides, and use of the distributive. You should be able to substitute values in the word problems and solve for the remaining variable.
Assignment: pg. 119-121: 15-21 odd, 47,49,71-77 odd, 84-94 even, 134-140 even, 161,162,167-168. For the equations, remember to show your work on both sides. The formula for each word problem is in the paragraph above the problem.
11-4 The homework on 2-step equations went well for most students but some need a little more review. If you had trouble with last night's homework, please try again now that we went over it. Remember that credit is given for showing both solving steps on both sides of the equation. There are a few additional problems that require simplifying on one or both sides before solving.
Assignment: Pg. 119-120 #14-60 even (if you didn't complete it already.) #68-78 even
Quiz on 3.1 on Wednesday
11-2 We reviewed the problems that will be on the quiz: checking equation solutions, distance rate and time formula, percent proportions, and 1-step equations, especially what work to show to get full credit. Homework is on 2-step equations. If your class notes aren't enough help, there are examples in the book on pg. 112 and 113
Assignment: Pg. 119-120: #14-60 even--show both solving steps on these equations.
10-29: More on applications of 1-step equations, including interest rate problems.
Assignment: Calculating simple interest worksheet #1-10; complete both sides of percent worksheet, homework credit given for showing the proportion and the crossproducts so that we are solving an equation; pg. 105 #137-139 (you must change the minutes given in the problem to a fraction of an hour.) Try pg. 119 #2-12 even, to see where we are on 2-step equations.
10-27: So, now that we remember how to solve equations, what kinds of problems can we solve with them? Distance, rate and time problems, percent problems, and interest rate problems.
Assignment: The Distance rate and time side of the worksheet #1-10 (workbook activity 41) you don't need to use 3 different formulas as the top of the worksheet does, you can use one and just solve the equation. And on the percent worksheet practice 9-5: # 9-14, 19, 23, 27--your work needs to show the percent proportion.
10-23: The second skill we will use in Chap. 3 is how to solve a 1-step equation, which is review from Algebra 1. The one step is to add, subtract, or multiply both sides of the equation by the same number to isolate the variable on one side. Instead of sometimes multiplying and sometimes dividing, we are trying to always multiply by the reciprocal to clear a coefficient.
When you solve an equation, no matter how easy it is, your work must show the original equation, and each operation to both sides, and the solution. Credit will not be given without showing this work.
Assignment: Pg. 102-104: #1, 32-56 even, 64-70 even, 76, 78, 84-90 even, 96, 104-116 even, 124, 126
10-21: We took a test today on Chap.2. To begin Chapter 3, we'll use our evaluation skills to substitute for x in an equation instead of an expression. If that results in a true mathematical statement such as 5=5, then the value of x that we substituted is a solution of the equation. You must show the substitution on each problem, and the resulting true or false statement.
Assignment: pg. 102-103: #4-22 even.
10-19:Well the results on the practice test don't bode well for the real test, so we went over every problem carefully. Students are doing more practice for homework, and the results should be much better. In addition to the assignment, students can get more practice by doing problems from the review that weren't assigned on 10-15, please check your answers in the back. It would help you to know right away if you're getting incorrect answers.
Assignment: Chapter test on pg. 85-86: #1-24. Again, you must write the problem, show work, and check your answer in the back.
10-15 Today students worked on a practice test for chapter 2, the real test is on Wed. the 21st. Students have a sheet detailing what's on the test and some problems from the chapter review for additional practice.
Assignment: You must write out the problem, and show a step towards your answer if at all possible in order to get credit. Pg. 83-85: #1-10, 17-26, 28, 32-37, 41-49. Please check your answers in the back. The answers to all review problems are in the back, that's part of the reason you don't get credit just for the answer
10-13 We took a quiz on section 2.1 and 2.2 today. And, we're finishing up chapter 2 with more translating of verbal expressions into variable expressions, but these have some like terms that can also be combined. We are also practicing writing 2 unknown quantities in terms of the same variable, which will really help with all our word problems in the next chapter.
Assignment: Front and back of the worksheet with the bad copy of the foot bones and the planet on the back. All the problems are in the book if you lose your copy. Pg. 75-76: #56-72 even, #95-103, and for challenge:106,107.
10-7 Quiz on Tuesday on sections 2.1 and 2.2, so more practice today on properties, simplifying like terms, and substituting for the variable to get a number, which we call evaluating. Remember that there's a link below to play a matching game with properties.
Assignment: Make a list of the 10 properties, and without looking in your book, try to give an example of each property, once with variables and once with just numbers. When you check your answers on pg. 58-60 in the green boxes, you will see they gave both types of examples. Also: pg. 67 #132-137, simplify and substitute 2 for the variable; #138-141 simplify and use (-1) for the variable; #144-149 simplify and use 5 for the variable.
10-5 We're translating english into algebraic expressions so that we can do real world problems. Remember that quotient means divide, and "the quantity" means you need to put it in parentheses.
Assignment: The "head on collision" side of the properties worksheet for more practice on simplifying and evaluating.
Both sides of the worksheet we started in class (firefly on one side) and pg. 73 #2-20 in the book.
10-1 We are practicing combining like terms because simplifying algebraic expressions and equations is a skill we will use all the time.
Assignment: In class we started: pg. 66-67: #23-24, #26-34 even, #42, #52-56 even, #70-80 even, #98-104 even.
In addition to finishing those: pg. 66-67: 36-40 even, 44-50 even, 58-68 even, 82-96 even, 106-118 even. (All broken up like that, it looks like more than it is!)
9-29 I hope you had a nice long weekend. Today we went over the properties of real numbers that allow us some flexibilty when we're simplifying and solving. There is an activity link below for some practice.
Assignment: Do the wrecker side of the joke sheet, and pg. 65-66 #1-20 all. I had 26-40 even on the board, but we didn't get to do that concept, so you don't have to do it for next class.
9-24 We begin Chapter 2 with some new vocabulary about variable expressions. Then we practiced substituting values for the variables in expressions to evaluate them(get a number for an answer.) This gives us more practice with order of operations as well.
Homework: Pg. 56-57: #13-61 just the middle column, #66, 70, 72, 76
9-22 The test went very quickly, I think it also went well. We began chapter 2 with some vocabulary that will help us work with algebraic expressions.
Assignment: read pg. 52-53 and write down definitions of the 8 bold words or phrases. On pg. 55, do concept review questions 1-6 and exercises 1-9.
9-16: Today we reviewed order of operations, which finished our first unit, Chapter 1. We also took a quiz on the second half of the chapter, not including order of operations.
Friday we will review for the test, which will be on Tuesday the 22nd.
Homework: (Don't use a calculator on these, it already knows order of operations.)On the worksheet Practice 1-2: #7-20 and #23-26. In the book: pg. 37: #30-41, 47-49, 54, and 58.
9-10: Today we reviewed operations on rational numbers which are in the form of decimals. We also rewrote fractions as equivalent decimals and percents, and back again.
Homework: pg. 29-30: #54-70 even and #84-96 even can be done with a calculator. #105, 108, 111, 114, and 126-139 by 3's are no calculator. #145 and 149 are with calculator.
9-3-09: We have a quiz next class (Tuesday) on section 1.1, 1.2, and adding fractions. Go over your notes and homework so you remember writing sets, using greater than and less than, absolute value, operations on integers, and addition of fractions.
Homework: pg. 29: #34-42 even, 46. Remember this is without the calculator.
