  1. There is not an actual grade suggestion, but it’s based on ability and interest. Building structures can be done by both younger and older kids just the complexity of the structure will change and the level of involvement your son puts into it. You could look up famous monuments to replicate or different types of bridges. He could build a more intricate pulley system. The possibilities are endless! FYI My son is in first grade.

  2. I definitely think so too. I want to share that everyone can do STEM projects even on a budget!
