These are the quick checks (two included) I created to see where my students are during our unit on factors, multiples, prime, composite, and divisibility unit. This helps me see which areas my class (or individuals) need more help with before our unit assessment. You could also use that as an in class assignment or a homework assignment.
~Factors (What are they and list factors of a number)
~Multiples (What are they and list multiples of a number)
~Prime Numbers (What are they and identify whether a number is prime WITH proof)
~Composite Numbers (What are they and identify whether a number is composite WITH proof)
~Divisibility Rules (Determine whether a given number is divisible by 2, 3, 5, 6, 9, or 10)
