Factors and Multiples Activities Bundle

Scaffold understanding of factors and multiples. Begin with arrays. Then list factors of numbers 1-100 with cards and worksheets. When kids are ready, move on to prime factorization. Finally, provide plenty of practice with a number of the day.

Open the previews to get a closer look at this bundle.

First, conceptualize factors, multiples, and common multiples with area models. Kids draw arrays for given numbers; consider additional arrays for some multiples; explore arrays for related numbers, and identify prime, composite, and square numbers.

Second, list factor pairs for whole numbers from one through one hundred. Kids use cards and worksheets to move toward fluency. They also identify each number as prime or composite.

Third, find prime factorization with factor trees and the ladder method. Kids learn to decompose a whole number and it as a product of its prime factors. This provokes deeper thinking about multiplication, division, and relationships between numbers.

Finally, reinforce factors and multiples with a number of the day. Twenty worksheets ask kids to decompose a number; list factors; identify it as even, odd, prime, composite, and/or square; and list multiples.
