Here are my rhythm cards and games (with instructions en français of course!). I use these all the time to solidify learning. I have included 3 games you can play with these cards that are suited for kindergarten to grade 2, but truth be told, my older students love them too!
It is also a great activity to leave for a substitute once they have played it a couple of times. This is the beginner package so there are quarter notes, quarter rests, and two eighth notes.
We start these games every so often in primary (teacher led of course). In grade 1 I let some of my musical leaders take over from time to time, and by grade 2, this becomes a totally student led activity. You can use it as a whole class or leave it for centers.
