You can hand out one case a day through the unit, or pull a single page when a group needs more practice with one skill. The mixed case at the end shows you quickly who can tell a factor from a multiple and a prime from a composite number. It also works for guided math groups, homework, a prime and composite review before a test, sub plans, homeschool lessons, and back to school or end of year review.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGrade Levels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWritten for 4th grade, where students find factor pairs, recognize multiples and decide whether a number is prime or composite, all with whole numbers to 100.
