Lesson 8 – Multiples and Factors
1. Composite number - a number that has more than one pair of factors.
2. Factor pair - two numbers that are multiplied together to give a product.
3. Factors of a number - whole numbers that multiply together to get the given number.
4. Multiple - the product of a given number and any other whole number.
5. Prime number - a whole number greater than 1 whose only factors are 1 and itself.
6. Factor - a number that is multiplied.
7. Multiplication - an operation used to find the total number of items in a given number of equal-sized groups.
8. Multiply - to repeatedly add the same number a certain number of times. Used to find the total number of items in equal-sized groups.
9. Symbol - a character, such as a letter or question mark, that can be used to stand for an unknown number in an equation.
10. Unknown - the value you need to find to solve a problem.
11. Divide - to separate into equal groups and find the number in each group or the number of groups.
12. Division - an operation used to separate a number of items into equal-sized groups.
13. Equation - a mathematical statement that uses an equal sign (=) to show that two expressions have the same value.
14. Factor - a number that is multiplied.
15. Multiplication - an operation used to find the total number of items in a given number of equal-sized groups.
16. Multiplicative comparison - a comparison that tells how many times as many. For example, 7 X 3 = 21 tells that 21 is 3 times as many as 7, and that 21 is 7 times as many as 3.
