  1. First Grade Enrichment class

    We solved the domino puzzle and got a sum of 14 on each side. We don’t think 11 or 12 are possible. Can you explain?

    • My first grade student also solved each side for the total of 14.

    • You are correct, 11 and 12 are not possible. But those are the possible solutions to the other Domino Window task if your students what to give it a try! Thanks for bringing this to my attention!
