I’ve been asking my 7th graders to work in teams of three on these Jamboards at the start of class. I created them using problems/puzzles from Don Steward’s incredible blog. I give them a new one each week and they work on them every day for about 10-15 minutes in breakout rooms with consistent groups. I’m hoping to build their fluency and also get them in the habit of puzzling their way through problems.
I will keep adding to the collection as I create them. (And okay, fine…#4 is not strictly number sense.)
