I am going to create a PE Newsletter this year for my Elementary students. I will include...

Units taught during that month
Skills & things parents can work on at home with their kids
A Health & Wellness portion
Community resources that correspond to the unit we are doing (Basketball camps or leagues in our community they can join)
Online resources for parents and students

I think your newsletter sounds great. I have never seen a PE teacher have a newsletter and what a great opportunity to help educate both parent and students. When I become a PE teacher, I too will send out a monthly newletter.
