Need to Problem Solve? Play with Marbles!

So, I'm working with some 1st graders during our Intervention/Enrichment time. I'm using code.org lessons... I LOVE THEM! This lesson is an unplugged lesson that centers around problem solving. Here's a little video to whet your appetite. I can't wait till our group meets again so all our kids can be successful and they can analyze why some designs worked the first time and others didn't.
