This is the best thing ever for math for kids. I absolutely love it because we don’t waste paper... I sometimes tutor my friends daughter and she used to go through like 20 pages each session. It was so ridiculous and a waste.This is easy to use and cleans easily. It is small so it is easy to bring with you.I keep this in the car so when I am not tutoring, my daughter uses it for car trips. It entertains her as she tries to write letters and draw pictures.This is amazing - honestly it is a parents best friend as if keeps sanity.
