A parent from my program gave me this activity she uses with her daughter to work on her scales:
Trader Joe’s sells alphabet cookies which her daughter loves, and if she can build the scale we are currently working on in the correct order she gets to eat the cookies! If some are out of order she doesn’t get to snack on those ones. (Now only if they made number cookies in there too you could work on fingerings to go with it!)Disclaimer: I am not ever a proponent of equating music to food or constant rewards, but sporadic rewards can be helpful if you use them sparingly and with instruction first. If they become consistent they are no longer effective. But if used correctly they can be fun!
