# Prime, Composite, and Factor Pairs Math Games

In this series of games, your students will learn how to find all factor pairs for a whole number in the range 1-100. The Prime, Composite, and Factor Pairs learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 4.OA.B.4 as written in the common core national math standards.

## Concepts Covered

All numbers used are whole numbers. All factor pairs are for numbers 1 – 100. Factors being found are 1 digit factors for numbers 1-100. Factors are numbers multiplied to get a specific product. Prime numbers have exactly two factors, themselves and 1. Determine if a number (1-100) is prime or composite by looking for factors. All even numbers greater than 2 are composite. The number 1 is neither prime or composite. Composite numbers have more than 2 factors. All whole numbers are multiples of each of its factors. Listing multiples to determine if a number is a factor is strategy to determine if a number is a factor. Find all factors of a given number, listed or written as factor pairs.
