### Factoring Puzzles

Here are a few examples of factoring puzzles:
Here's the same set up for factoring a trinomial.

Factoring with a > 1 is not much harder, when students remember to find factors of ac that add up to b. Those become the insides of this table, and factoring out GCF's leads to the outsides, and the final factors.

1. Thanks for sharing your puzzles - they are a great idea. I arrived at your blog via Dan Meyer's post (and your comment) on Factoring Trinomials/Headache/Aspirin, etc. All the theory aside, I think many students like to solve puzzles, and one key to engaging them with factoring is to play up the puzzle aspect. One question - the file for Table Puzzles (Multiplication) is actually an answer key - do you have a blank copy of the file? I would love to 'borrow' these worksheets. - Wendy Menard
