Love the idea - LITE version indeed! – Montessori Hundred Board Lite Review

The LITE (or free) version should at least let you go all the way to 100. After 25 you click 26 and it counts as incorrect and takes you to the "buy the full version" screen. As a 'Montessori mom' I think these apps are a fun way to reinforce what they're learning in school when away. I do also think the numbers need to be randomized in the 'tray' each time too - otherwise it's a not learning, but memorizing a location!
