Factors Reference (Prime and Composite)

This is an updates version of my free download with errors corrected. The first page has factors for composite numbers listed in their factor pairs. The second page is a reference for PRIME and COMPOSITE numbers.

This page is helpful for students who struggle with the memorization of their multiplication facts but still need an easy to use reference to be able to work with fractions, complete mental multiplication and division, and helps build number sense. This can also be used to help support new teachers as they learn the ropes of teaching elementary math concepts. Building our own number sense better prepares us for supporting our student's learning.
