I personally use a strap less heart rate monitor and find that it is pretty accurate. I believe that grades 4 to 6 would have no problem using them. Of course the biggest concern would be cost, but if you have put in for a grant it looks like you have that part covered.

I am interested if you have heard back yet about your grant and which grant in particular you applied for

ryan, what grant did you put in for. i am also looking into grants for acquiring techno toys, but am not sure where to start. thanks, ralph
