Community reviews for Montessori 1st Operations

I wouldn't give this to a child to learn on their own. I would say the concept should be taught previously and then this can be the review and practice. This app allows you to set up different accounts. I only had 2 different students, so I do not know if there is a maximum allowed. It also gives a nice review for parents. If parents ask for a math review, I would suggest this game. However, there are other math apps that students had more fun with.
