A couple of years ago, I picked up a game, Crazy 8ths for the studio and I've been really happy with the purchase. Over the years, I have used this set of games many times and it has become a studio favorite. Of course it helps that when my students play against me, I never seem to win (hmmm...).
There are several different games to play with this set of cards so it's easy to pick out a game that works for an individual student or a group of students. The actual game of Crazy 8ths is my personal favorite since it helps reinforce note names in various places on the grand staff.
The pictures on the cards lend themselves to a younger group of students, but some of my teens have played the game and don't seem to mind or even notice. The cards include a repeat sign letting the player have an extra turn, a quarter rest sign which forces the next player to lose a turn and a triplet card requiring the next player to draw three cards if they don't have a triplet card of their own. This game is especially fun with a group of kids because there is also a "musical chair" card that when it is played requires everyone to change their seat and play with someone else's cards. That really adds to the fun!
