Personal SpeedMath Plus - Version 1.2 Personal SpeedMath Plus is a series of math drills designed to enforce memorization of basic addition, subtraction, multiplication and division. Personal SpeedMath Plus has been tested and proven to increase basic math skills in children ages 6 and up. Children who normally count to obtain a correct answer are motivated to recall the correct answers from memory even when faced with the same problems in real life situations. Your children will benefit from their own natural tendency to compete by trying to outperform scores of their peers or even their previous scores. Your children's self-esteem will increase each time they exceed their previous "high score". The SpeedMath Challenge gives children a reason to perfect their skills; to see their name in the SpeedMath Hall of Fame and hearing the rewarding applause for their accomplishment. A good understanding of mathematics is essential to a more complete understanding of many other subjects such as art, history, language, music, science and many more. Includes Digitized Voice, Digitized Sound, High Scores and the SpeedMath Challenge!
