My 5 year old loved the Learning Resources Code $ Go Mouse STEM Activity set. Coding is not an easy skill, I think this activity helps simplify the logic, strategy and overall thought process that goes into it. The set comes with 83 pieces, most of them are idea cards, and walls and also code cards for directions, the cool thing was the maze pad itself which can be made into many designs and also the mouse is super cool my son loved playing with it. We are enjoying this set and are thankful to Chatterbox and Learning Resources for allowing us the opportunity to try it out free of charge.
