This website describes itself as pre-algebra from another dimension. Students can practice their problem solving skills with these interactive games that take place in a variety of places in the Absurd Math Dimension. There are several levels requiring calculations that allow you to move on in the game, accumulating clues and solving the puzzles. Use the calculator provided, and get help if you need it. Teachers and parents can even get the answer keys, if necessary.
