| argument | a reason or reasons offered for or against something; suggests the use of logic and facts to support or refute a point |
| associative property of addition | the sum stays the same when the grouping of addends is changed |

| evaluate | to examine and judge carefully; appraise |
| even number | a whole number divisible by two |
| evidence | models, known facts, patterns, relationships, and counterexamples |
| expanded form | a number written in component parts showing the cumulative place values of each digit in the number |
| fact | a basic mathematical statement involving numbers and operations |
| factor | one of two or more numbers that are multiplied together to obtain a product |
| identity property of addition | adding zero to a number gives a sum identical to the given number |
| identity property of multiplication | multplying a number by 1 gives a product identical to the given number |

| perimeter | the distance around the outside of a shape or figure |
| place value | the value of a digit as determined by its place in a number |
| predict | to tell about or make known in advance, especially on the basis of special knowledge or inference; to make an educated guess |
| product | the result of a multiplication expression |
| quotient | the result of dividing one number by another number |
| reasonable | within likely bounds; sensible |
| remainder | the undivided part that is left after division; it is less than the divisor |
| represent | to present clearly; describe; show |
| revise | to chang or modify based on guess and check or on reflection and evaluation |
| solution | result; answer; the process of finding the answer |
| solve | to find an answer or solution to a problem |
| standard form | a number written with one digit for each place value |
| standard units of measure | units of measure commonly used, generally classified in the U.S. customary system or metric system |
| strategy | a tool used in problem solving, such as looking for a pattern, drawing a diagram, working backward, etc. |
| sum | the result of addition |
| symbol | a character used to represent operations, numbers, or relationships between numbers |
| validate | to substantiate, verify, or confirm |
| verify | to establish as true by presentation of evidence |
| whole number | any counting number or zero |
| word form | the expression of a number in words; reading the symbols |
| zero property of addition | adding zero to a number gives the sum identical to the original number |
