I can't take any credit for this idea. I saw it a while back BP (Before Pinterest) and now I can't find the teacher's website who had a great monster painted on a commercial sweeper.
If you know, send me a message.
I painted this over the summer and it is great to see students get excited to clean. I find a student that needs a job and say quietly, "Hey, you wanna be our monster sweeper today?" They often pick a partner to help. I should have come up with something like this for
my own kids when they were young!
