Personal Trainer: Math
The game isn't a teacher, but a good reviewer.
I teach math to high school students (different skill levels) and bought this game hoping it'd be an alternative to "teaching" students who lack basic math skills. Instead, I found a game that helps brush up the player's speed when it comes to computational work (addition, subtraction, multiplication and division). For an educational math game, the graphics are very good--not too distracting to the player. The game can be played both left-handed and right-handed, however, once you create a profile, you cannot change the hand-writing set-up (left/right hand). The frustrating thing about this game is how numbers are read. The numbers that are usually mis-read whenever my students write them are 2, 4, and 7. The game does not "teach" how to add, multiply, divide or subtract--it expects you to know these things already. The focus of the game is to see how fast you can write the answer and if you know the right answer. To put it simply, the game transforms worksheets and flashcards into a "game"--how fast can you finish the exercise and how many answers can you get right? Aside from that, Personal Trainer: Math is a very useful tool in the math classroom for reviewing students. You can either take a daily test, do kageyama method (addition, subtraction, multiplication, and division drills), or practice exercises (varying levels of difficulty). All three aspects of the game make it a definite "must-have" for those who simply want to improve mental math skills. I've yet to try the group study feature, but my students have played this game in class and found it to be fun--they compete with each other to see who can finish with the fastest time and 100%. People who've taken higher level math (geometry, trigonometry, calculus, etc) might find this game to be TOO BASIC. However, if you're not confident about your math skills but want to improve, this game will be a good addition to your DS library.
