Absolutely Amazing!! Both my 8 yr. old and 10 yr. old daughters have found this software entertaining, challenging, and educational. The software has four different skill levels that is challenging to both their learning needs. You can either play the game with Mia Mouse or just do the activities.If you're an adult, don't be discouraged by the interface - it's not for you, it's for your child. They will love it, listen to the instructions and figure out how to make Mia move and find clues.I initially sent this back, tried three other programs and finally came back to this as the best math software available for 3rd and 4th grade girls!
