Montessori Numbers – Math Activities for Kids for iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) and iPad on the iTunes App Store.
This is the first time this app has ever been offered for free. (Normally, $2.99) This is a top rated, award winning app that introduce young children to numbers and build number sense. I bought this app a long time ago when it was on sale. It is a pretty great introductory app that build on early math skills and can be used for a pretty long time as the quantities activity is really useful for teaching place value and grouping skills. This is especially useful when you just don’t feel like pulling out the linking cubes or cuisenaire rods.
Highly recommended for ages 3 to 7.
