This is a unit on factors, prime numbers, and composite numbers. The first and second pages have definitions and examples of factors, prime number, and composite numbers, plus numbers where students are asked to find all of the factors of the given numbers. The first page also has two hundreds charts where the students can identify all of the prime numbers on one chart and the composite numbers on the other chart. The third and fourth pages are sorts where students can cut, sort, and paste the given numbers into prime and composite numbers. The fifth through eighth pages are a pretest and posttest. I have increased the rigor to match the updated state standards. The pre/post test each have five multiple choice questions, three multiple mark questions, one question where the students write the numbers on a chart identifying if they are prime or composite numbers, and one question that ask students to list all of the factors for the given numbers listed.
This matches the VA fifth grade math SOL 5.3a,
