- In fourth grade, kids need to gain familiarity with factors and multiples. This set of activities asks students to conceptualize with arrays, find all factor pairs for the numbers 1-100, and determine whether a number is prime or composite. Number of the Day pages provide ongoing practice.This resou$9.00$11.00Save $2.00
Twenty different worksheets ask students to decompose a number using prime factorization; list all factors; determine if the number is even, odd, prime, composite, and/or square; and list some multiples of the number. It forces them to manipulate the number and think!

How to use:
- 4th grade – Once your students have had practice finding factors, use one sheet each day to help them fully master CCSS 4.OA.B.4.
- 5th grade and beyond – Use to help students grasp multiplicative patterns. It’s great for tutoring or helping students find equivalent fractions.
Prime factorization really builds conceptualization. Try it!
