  1. 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

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!

To support classroom, hybrid, and distance learning, this resource is included as a printable PDF and interactive Easel Activities. Open the preview to take a look.

What’s included:

  • rules of divisibility reference sheet (color and grayscale)
  • definition sheet (color and grayscale)
  • guide to using factor trees (color and grayscale)
  • 20 number of the day sheets (grayscale)
  • answers

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!

Enjoy Teaching!
