Want to use my puzzles in your class? Feel free to do so! I only ask a few things in return:
If you want me to hold back the solution for any puzzle that you plan to use, please let me know ahead of time. Otherwise I may honor requests for solutions and accidentally help some students cheat.
If you would like a copy of a puzzle without my blog header and contact info, please contact me and I'll do my best to provide a PDF that meets your needs.
If you would like more puzzles of a particular type, easier or harder puzzles of a type, or some other custom request for puzzles, worksheets, or other materials, please contact me. I'm happy to help for free as time permits.
