Reviewer Comments:

The content presented here is sets of numbers (no real or irrational), prime & composite and divisibility. The CRT feels this would be great background information for any lesson presented from grade 3 through grade 9. Whether you are covering sets of numbers for the first time or introducing domain, possible answers to expect from a solution or divisibility this pdf file gives links for further resources and a cute history starter about counting sheep. There are some ‘Your Turn’ questions provided at the end of the document for possible classroom assessment.
