### 65 and Factors, products, primes and composites

65 is a composite number. 65 = 1 x 65 or 5 x 13. Factors of 65: 1, 5, 13, 65. Prime factorization: 65 = 5 x 13.

This post is an excellent example of how the FIND THE FACTORS puzzles can be included in mathematics instruction. I really liked the students’ description of what they did in class with the puzzles.

There are two easy ways to copy the puzzles for use in the classroom. If you click on any of the excel files that contain 6 puzzles, you will find all 6 puzzles available in two different print sizes: 6 small ones per page or 2 large ones per page. You can also copy any jpg picture that is on the blog, paste it onto a word document, and then make the picture as big as you want on the document. The excel file will probably give you a cleaner copy though.

If the only way you can access the puzzle is on a device that isn’t connected to a printer, you will probably have to hand draw or reproduce a copy of the puzzle as 6è Primària did in order to use it. That requires real commitment!

Please include the puzzle title and copyright information when you make copies for the classroom or any other non-commercial use.
