Only useful as an example of the paid version – Montessori Hundred Board Lite Review
Great simple chart, but the lite version is not very functional. It does not let you count to 100. I sat down with my 4 year old to do this and was disappointed that after hitting number 26, the screen changed, asking if I wanted to buy the full version.
