Kids will want to practice their math on this portable skill-building ELA that turns maths into a video game.

MathShark quizzes eight different skill levels in addition, subtraction, multiplication, division, fractions, decimals, and percentages, and works as a full-function calculator with the press of a button.

Problems are displayed on the LCD screen either vertically or horizontally. Answers receive immediate feedback with colorful flashing lights and tones. Sets are timed, and the elapsed time plus a message appear at the end of each set. As they see their time improve, kids are continually motivated to beat it, just like when they play a video game.

The more they play, the more they learn.

Requires two "AA" batteries (not included). Measures 10" x 6.1" x 3.9".
