MathLands integrates puzzles, problem solving and an environment of trial and error to develop mathematical intuition. Activities challenge adult users, but are supportive to helping kids get to the correct answer while understanding how they did it! There is no sound, so children will need to read to know what they are solving for. Each game gets slightly harder as you play and the hints are not especially instructive. This app has the potential to challenge and encourage a "stick with it" attitude for your kids - especially if you play it alongside your child. In the newest version hints and solutions are now only available with an in-app purchase.
