I kinda like the idea of using the plastic bubbles but I noticed that a lot of the primary grade teachers were giving input. I teach fifth and thought about incorporating them this way. I have a Candy Grabber which is basically a mini prize machine where you have to move the arm to pick something up. So I was thinking of using it to take "brain breaks" after a long Reading, Math or Writing block. I would act like a game show host and call the number of the lucky student to "come on down" and grab a bubble. Inside I would place small pieces of paper with things like 1 minute dance party, do 10 jumping jacks, 10 toe touches, etc. Anything to last a minute and get them to moving before returning to their assignments. I think I will really need this during the first two weeks of school when everyone is still sleepy at 10a.m. So what do you think about this idea?
