| A | B |
|---|
| 35=5X7 | five times as many as seven OR seven times as many as five,  |
| prime number | the only way to get the number is times 1. Example would be 5- the only way to get 5 is 5X1 |
| composite number | there are many different ways to multiply two numbers together to get it. An example would be 12. YOu can get 12 by going 6x2, 3x4, 12x1 |
| factors | all the ways to get a number. Example of 16 would be 1x16, 2x8, 4x4 |
| multiples | all the numbers you can get by multiplying by a certain number. Example would be the multiple of 4 are 4, 8, 12, 16.... THE SMALLEST MULTIPLE WILL ALWAYS BE THE NUMBER ITSELF (NEVER 0 OR 1) |
| fractions are the same as | division |
| expanded form | breaking the number up into its individual place values. Example would be 1234 = 1000 + 200 + 30 + 4 |
| area | length times width or the number of squares in an object,  |
| perimeter | adding up all the sides on the outside,  |
| array | how to visual show what an equation would look like as a set of squares; a 3 by 4 array would equal 12,  |
| remainder | can never be as big as the divisor; if it is than you can share the item one more time |
| equivalent fractions | take up the same amount of space; can cross multiply to check to see if the same,  |
| subtraction answer | to check go in reverse and add the answer to the amount originally subtracted |
| divison answer | to check the answer multiply the answer times the divisor and add the remainder back to it |
| decompose fractions (different ways to get the answer) | 7/8th = 1/8th + 6/8ths or 3/8ths + 4/8ths |
| addition or subtraction of fractions | must have the same denominator to do this,  |
| tenths | equals dimes or 1/10th or .8 (first number after decimal),  |
| hundredths | pennies or .09(second number after decimal) or 1/100ths, |
| .78 | seventy eight hundredths or 78/100th |
| .90 | same as .9 or 9/10ths or 90/100ths |
| comparing things | IF you are comparing fractions or decimals they must be using the same whole amount to make the comparison; I can say that I have 1/4th of a Kitkat and Kayla has 2/4th of the Kitkat; we know who has more because we are using the same whole object |
| 1 kilometer (km) | the same as 1000 meters; about half a mile; used to measure big things like distance between cities,  |
| centimeter (cent =100) | it takes 100cm to equal 1 meter |
| kilogram | equals 1000 grams; equal about 2 pounds; measures the weight of things that are pretty big like steak, people, boxes |
| gram | weighs about the same a paperclip; weight of things that are small; it takes 1000 of these to equal a kilogram,  |
| ounces | it tiakes 16 ounces to equal 1 pound (lb); a can of Coke is 12 ounces |
| ton | equals 2000 pounds; think about weighing elephants, cars, trucks,  |
| seconds | 60 in a minute; 3600 in an hour |
| minutes | 60 in an hour |
| liter | equals 1000 milliliters (ml)- measures liquids like Coke (2 liter) |
| milliliter (ml) | used to measure the amount of medicine you should take; think of drops from an eyedropper,  |
| 2 minutes = | 120 seconds |
| 3 pounds = | 48 ounces |
| 5 hours = | 300 minutes |
| 7 feet = | 84 inches |
| circle | 360 degrees |
| quadrilateral | 4 sided object;360 degrees,  |
| triangle | 180 degrees |
| right angle | 90 degrees,  |
| acute angle | less than 90 degrees; Pacman |
| obtuse angle | more than 90 degrees; pool chair |
| half circle | 180 degrees |
| line of symmetry | a line that splits an object in half so it can be folded over on itself,  |
| right triangle | triangle with a 90 degree angle in it, |
| scalene triangle | no angles or sides are the same |
| equilateral triangle | all sides and angles are the same,  |
| isosceles triangle | 2 sides or angles are the same |
| perpendicular lines | two lines that connect to make a right angle,  |
| parallel lines | two lines that will never meet like railroad tracks |
| intersecting lines | lines that cross |
| ray | a beginning point but not an end point,  |
| line segment | has a beginning and end point, |
| endpoint | a dot |
| vertice or vertex | the angle where two lines meet; it is always the middle letter in something like this <abc = the vertice is b,  |
| sum | answer to an addition problem |
| difference | answer to a subtraction problem |
| product | answer to a multiplication problem |
| quotient | answer to a division problem,  |
| divisor | how many groups you are sharing with: the remainder came never be as big as this, |
| dividend | what you are sharing, |
| about | estimate |
| denominator | bottom number in a fraction; remember that the bottom number tells you how many people you are sharing with; the more you share with the smaller the piece you get,  |
| numerator | top number in a fraction, |
| mixed number | the whole number plus the fraction of another,  |
| improper fraction | all the pieces you used over the counting number, |
| trapezoid | a quadrilateral with one set of parallel lines |
| rhombus | quadrilateral that looks like a slanted square; diamond |
| pentagon | five sided object |
| hexagon | 6 sided object |
| meters, feet, inches | measure distance or length |
| liters, gallons, quarts, and pints | measure liquids |
| grams, pounds, tons | measure weight |
| ounces | liquid or solid |
| milli- | really small |
| Kilo- | really big |
| Lines of symmetry | if sides are all the same then the the number of lines of symmetry is the same as the number of angles |
| reflex angle | more than a half circle but less than a whole circle,  |
| estimation | round to the biggest place; as many zeroes as possible,  |
| Constructed Responses | can use unknowns and timelines to round,  |
| fractions, decimals, percents | think of money for decimals; decimals and percents are the same,  |
| 3 X 1/4th | Multiplying a whole number times a fraction is just the same as repeated addition with the denominator staying the same,  |
| line plot | make sure to look at the labels on the side before answering the question,  |
| decimal rounding with a line | make sure to think in terms of money, |
| gallon | 4 quarts,  |
| pints | 2 cups,  |
| quarts | 2 pints,  |
