Our boys like to build and LEGO is a big hit. So I had an idea to incorporate LEGO blocks into our math lessons.
For this LEGO addition activity, you can just handwrite plus sign and equals sign on a white paper, give them some LEGO blocks and let them build their own equations.
Make sure you choose blocks that are suitable for the level your kids are comfortable with. If you give them bigger blocks, the addition will end up go over 10. But if you kids are advanced, give them higher numbers!
