My son is in Kindergarten and has been getting build boxes since he was in preschool. He loves knowing how things work. Initially he struggled a little with the build, however now he can do them himself. He always watches the videos with the build. When he makes a mistake he figures it out. He also breaks his builds and then rebuilds them. He already wants the hack box! Every month he gets so excited to get his box and always looks for the ticket to crunch labs. This has saved many gadgets around my house from being taken apart to see how they work!! Thank you Mark Rober! He made you a video. I included the link.
