All I can say is WOW! MathLands is a completely FREE educational math app that makes kids THINK! Kids have to use logic, problem solving skills, and critical thinking to solve 5 levels of 5 different puzzles. Each puzzle is timed, has hints available, and has a section that tells the history of the puzzle. Kids can choose to start over. They can try again to get a better score or they can try again to get the BEST score (the app tells what is the best possible score). I love that this app challenges kids to be the best!! There is also a Math Comics section – problems are written in comic strip form. Kids solve the word problems by using the interactive manipulatives on the page. In a word full of math apps that stress practice and drill, this app is like a breath of fresh air. LOVE it !!!!
