Product Description
These number of the day sheets are for big kids! Twenty cards ask older students to decompose a number into its prime factors; 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!

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)

How to use:
• 4th grade – Once your students have had practice finding factors, use one sheet each day to help them fully master 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 is a sure-fire way to find all factors of a number. (And it really builds conceptualization.) Try it!
