About this worksheet
Sentences like "6 is a ___ of 54" to finish with factor or multiple. More adds neither.
What kids practice
Factors are numbers that multiply to make another number. The factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. Multiples are what you get when you skip count, like 6, 12, 18 and 24. A prime number has exactly two factors, 1 and itself, and a composite number has more than two. Fourth graders find factor pairs for numbers up to 100 and sort them as prime or composite.
Watch for
- Missing a factor pair, especially in the middle, like 4 × 6 for 24.
- Calling 1 a prime number. It has only one factor, so it is neither prime nor composite.
- Thinking every odd number is prime, like 9, 15 or 21.
- Mixing up the words factor and multiple.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full factors and multiples guide for 4th grade.
