Does your child know the difference between prime and composite numbers? This worksheet explains prime and composite numbers. Then, they are presented with six trays of donuts. They need to figure out the factors for the number of donuts. After they count how many factors there are, they can determine if its prime or composite.

To figure out if a number is prime or composite, we need to find its factors, which are numbers that can multiply together to equal the original number. Let's use the number 8 as an example. The factors of 8 are 1, 2, 4, and 8 because 1 x 8 = 8 and 2 x 4 = 8. Since 8 has more than two factors, it is a composite number. Now, let's look at the number 7. The factors of 7 are just 1 and 7 because only 1 x 7 = 7. Since 7 has exactly two factors (1 and itself), it is a prime number. Prime numbers have only two factors, while composite numbers have more than two factors.
