Whatever you do for a brain break it needs to be something to re-energize your kids and bring their focus back to learning. I have found some great short learning videos that have music and some basic skills all wrapped together. Here are a few of my favorites. The first one is my classes favorite.
If you haven't heard of Mr. Harry's Kindergarten, just go to youtube to see all his videos or visit his website to download his songs.
I just read that he will be at I Teach K in LAs Vegas next summer. I can't wait to see him.
