    Lesson 8 – Multiples and Factors

    1Composite 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.

    9Symbola 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.
