No matter how old your kids are, they are probably playing with LEGOs. Mine still are at 9 and 11!
After the Christmas season, we found ourselves with more LEGOs than I thought was possible to have in one house at a time! Instead of just using these LEGOs for playtime, we found a way to incorporate learning with them!
These LEGO STEM challenges are perfect for stretching your brain and making learning fun.

Here are 20 LEGO STEM challenges for kids. These can be done in the classroom, as a homeschool activity or just a way to keep your kids learning outside of school.
