After thinking about it for a bit, I decided to use them for rhythm dice. I created a set for 1st grade using quarter notes, eighth notes and quarter rests. I used a sharpie to mark the sides of the dice with the notes/rests.
I used them with first grade for the first time this week and they really enjoyed them. I don't really have a name for the game but this is what we did:
Each group had 5 dice.
They had to create a 4 beat rhythm using their dice.
In order to do this they rolled all the dice to see what they got.
Then they could throw a beat away to create their 4 beat rhythm.
The whole group then played the 4 beat rhythm before the next turn.
There were two things I loved about this game. The dice reinforced eighth notes receiving one beat and students had to use the name of the note/rest they were tossing out.
This was very easy to set up and play. The kids each had several turns to create a rhythm and it only took about 10 minutes from explanation to clean up. This is something I could pull out when we have extra time to help reinforce rhythm. Or, it might be a nice center if you added notating their rhythms.
