Math Shark

The portable skill-building Math Shark quizzes 8 different skill levels in addition, subtraction, multiplication, division, fractions, decimals and percentages AND works as a full-function calculator. Problems are displayed on the LCD screen and answers receive immediate feedback with lights and tones and a "help" key provides clues for solving problems. Sets are timed and the elapsed time and a message appear at the end of each set. As they see their time improve, students are motivated to beat it. The more they play, the more they learn! Requires 2 AA batteries (not included).
