Terms | Definitions |
|---|---|
 addend | the name for the numbers that are added in an addition problem |
| addition | the process of finding the total number of items when 2 or more sets are joined |
| ascending order | the order of numbers or objects from least to greatest |
| associative property | this is the property in which the same addends (or multiples) can be grouped in different ways and the sum (or product) will be the same |
| commutative property | this is a property in which the order of two or more addends (or multiples) can be changed and the sum (or product) will be the same |
| compare | to determine if two quantities are greater than, equal to, or less than each other |
| decimal | part of a whole; shown with numbers and a decimal point |
| decimal point | a point that separates whole numbers and decimal numbers |
| descending order | refers to numbers or objects that are in order from greatest to least |
| difference | the answer to a subtraction problem |
| digits | the ten symbols used to write a number (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) |
| dividend | the number that is divided in a division problem |
| division | a process of sharing a number of times to find how many groups can be made |
| divisor | the number that divides the dividend |
| equal parts | when a set or object is divided into the same parts |
| equal sign | a symbol that shows two amounts have the same value |
| equation | a number sentence that shows two quantities are equal (=) |
| equivalent | sets that have the same value |
| estimate | to find a number that is close to an exact amount; to give an approximate value rather than an exact answer |
| factor | a number that is multiplied by another number to find a product |
| greater than | the symbol >; shows the first set is larger than the second set; also more than |
| inverse operations | operations that undo each other; addition and subtraction; multiplication and division |
| less than | the symbol <; shows the first set is smaller than the second set; also fewer |
| minus | the symbol - ; shows subtraction |
| multiple | a product of a whole number and another whole number |
| multiplication | the process of finding the total numbers of objects in equal-sized groups |
| period | A group/family of 3 digits in a number; separated by commas starting from the right |
| place value | the position of a digit in a number that is used to determine the value of the digit |
| plus | the symbol +; shows addition |
| product | the result of multiplying two numbers |
| quotient | the answer in a division problem |
| regrouping | the name for the process of exchanging amounts equal in value to rename a number |
| remainder | the left over amount when a number cannot be divided equally |
| round | to increase or decrease a number to the nearest ten; a process that tells which multiple of 10; 100; 1000; etc. a number is closest to |
| subtraction | the process of taking away objects from a group |
| sum | the answer to an addition problem |
| whole numbers | the set of numbers that start with zero |
| standard form | the form of a number written with commas separating groups of 3 digits starting from the right; Ex. 345, 720 |
| word form | The form of a number written in words using place value Ex. three hundred forty-five thousand, seven hundred twenty |
| expanded form | Thee form of a number that shows the value of each digit; Ex. 300,000+40,000+5,000+700+20+5 |
| minuend | The number being subtracted from |
| subtrahend | the number being subtracted from the minuend |
| Identity Property of Addition | The property that states: the sum of any number & zero is that number; n + 0 = n |
| Identity Property of Multiplication | The property that states: the product of any number & one is that number; n x 1 = n |
| underestimate | The result of using smaller numbers to estimate a sum or product. The estimate is smaller than the actual answer. |
| overestimate | The result of using larger numbers to estimate a sum or product. The estimate is larger than the actual answer. |
| Commutative Property of Multiplication | The order of factors can be changed and the product remains the same. 3x5=5x3 |
| Commutative Property of Addition | The order of addends can be changed & the sum remains the same. 3+7=7+3 |
| Associative Property of Multiplication | Factors can be regrouped & the product remains the same. |
| Associative Property of Addition | Addends can be regrouped & the sum remains the same. |
| Zero Property of Multiplication | In multiplication, the product of a number & 0 is 0.Ex. 8 x 0 = 0 |
| equivalent decimals | Decimals which name the same amount. |
| equivalent fractions | Fractions that name the same part of a whole region |
| tenth | one part in 10 equal parts |
| hundredth | one part in 100 equal parts |
| ...its right | Each place is 10 times the value of the place to ____ |
| exact | the actual, precise number (sum, difference, product,quotient); not an estimate |
| pattern | A series of numbers or figures that follow a rule |
| reasonableness | when an answer makes sense |
| front-end estimation | A method of estimating by changing numbers to the place-value of their front-digit & then finding the sum or difference |
| variable | the name for a letter or symbol that stands for a number or set of numbers |
| algebraic expression | a number sentence that includes a variable (no =) |
| evaluate | to find the value of a numerical or algebraic expression |
| even numbers | any number that can be evenly divided by two |
| odd number | a number that cannot be evenly divided by two |
