PE Fit! This is a program developed by a teacher to be used in schools. Check out her website:
OK, so I asked this question a loooong time ago, but I wanted to let anyone interested know, after reviewing the suggestions as well as continuing to look, we (my boss and I) found a WONDERFUL curriculum to use. It is called Kid Fit. www.kid-fit.com
It offers fitness in a fun, yet challenging, way appropriate for their age level. It also helps to build important things such as balance, coordination, and team work – all of which are important skills to master and especially during this time in their lives.
Thank you so much for your help in my search!
