      This a great activity for my 8th-grade students to play while I was checking homework in class. I had to give the student groups new numbers as they solved each problem, but they were very engaged in working on the problem. The students requested to play again.

        This is a great idea Erin. Thank you for sharing – there’s never enough ideas to help us all fill-in idle time a little more productively.

      Got to play that recently.. quite the challenge if you are up to it. We as a group were and managed to solve it. Great lesson in “working with the hand you are dealt” or finding creative ways to solve an issue with the tools you are given.. tools being all the mathematical symbols or selective symbols depending on the groups age and ability
