My five year old is very into STEM activities, and since my husband is an engineer we've been very enthusiastic about supporting and encouraging those interests. The code and go mouse is a great way to teach basic concepts of coding while still holding the interest of an energetic kindergartener. He has a blast completing the successively more difficult mazes we'd create, and he was so proud each time the mouse reached the cheese. This a great quality, very engaging toy, and our entire family enjoyed it. It's definitely one we'll be bringing out frequently!
