I received the Code & Go Robot Mouse Activity Set for free in exchange for my honest review. My children, 7 and 5, LOVED it! They thought Colby the Mouse was so cute. More importantly, I LOVED it! Watching my son, who gets frustrated easily, calmly sit and rework the coding in order to get Colby to the Cheese was a dream come true. It taught him some real world problem solving skills, critical thinking skills, and that there is no shame in having to start from scratch in order to get the result you want. I was so proud watching him CALMLY find a solution when Colby ran off course. So glad to have found this set, and I would have definitely paid full price for it. The kids enjoy creating mazes based on the cards provided, or creating their own.
