TappyTaps has introduced Bubbling Math 1.0 (http://bubblingmath.com/) an education game for children in first through fourth grades. It works with Mac OS X 10.6.x and 10.7. The game is available for US$1.99 through the end of September and can be found in the Education category of the Mac App Store.

Bubbling Math helps kids practice elementary math operations. It sports a module that allows parents to choose which types of tasks they want their children to practice and to review wrong answers afterward.

Bubbling Math contains nine different graphics levels. In each level the child can receive an award -- bronze, silver or gold cup -- motivating children to play the game over again to try and improve their score.
