Lesson 4.OA.4

Concepts addressed:

• Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factor

• Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number or a factor of a larger number

• Determine whether a given whole number in the range 1-100 is prime or composite.

Key terms for this lesson:

• Factor - a number that may be multiplied with another to make a product

• Multiple - a number that can be divided by another number without a remainder.

• Whole Number - a positive number that doesn't have a decimal e.g. (0,1,2,3,4)

• Divisible - a number that is able to be divided by another number, WITHOUT a remainder

• Prime - a positive number with only 2 factors (one and itself)

• Composite - a positive number with more than 2 factors

• Factor Pairs - a pair of numbers that are multiplied together to get the multiple of each number
