These are task cards I created to use to check for mastery with factors, multiples, divisibility, prime, and composite. These are designed with 4th grade in mind, but they could be used in other grades are remediation, pre-teaching, or extension. Each is open ended to ensure they are not just guessing the answer and not really taking the time to work them out.
~Greatest Common Factor
~Least Common Multiple
~Defining the terms, factor, multiple, prime, and composite
~Determining what a number is divisible by
~Determining if a number is prime or composite with proof
These could be used as individual practice, an assessment, a group activity, homework, or for an early finisher.
I hope your class gets great use out of these task cards!
