I’ve been a PE teacher for nine years and a CrossFitter of almost 4 years. I am Level 1 and CF Kids certified and I use CF in with my PE classes. I wanted to share some of the things I have picked up over the years about CF in the high school setting. I believe that they pertain to middle school as well but not elementary. The link is to a google doc that I welcome anyone to use and also to add their own tips and experiences. I hope you will find it useful.

This is wonderful! Thank you so much - I already learned a few things that I would like to implement with my students. Thanks!
