Just like most "Train your brain" games, Professor Kageyama’s Math Training also offers you a daily test. If you were present, you get a mark in your calendar. After turning your DS like a book, you start with a few sums with numbers beneath ten and illustrations with a number of objects. The goal is to write down how many there are as soon as possible (maximum ten).

Enjoy it, because it's the only visual exercise you will find in this game. The rest is numbers, numbers and more numbers. After getting five marks in your calendar, you level up but it will still only take you about five minutes to complete the test. And then you're very slow...

The so-called 100 cells method allowed the Japanese professor to put his name in the title. You choose the size of the grid (10, 30, 50 or 100 cells) that has numbers between 0 and 9 (or 20 if you're going to subtract) on the top and the left. All you have to do is fill in the results in the corresponding cells. As in the other modes, you get a bronze, silver or gold medal according to how many answers you got right and how fast you completed the exercise.

Dividing was a bit hard to put in a grid, so they made a separate section in the Kageyama Method mode. You choose the difficulty – Easy, Normal of Hard – and the number of exercises you want: 10, 30, 50 or 100. As it happens, you're able to play everything in this Kageyama Method mode with fifteen other players, while you only need the game once.

The last mode is the practise section, where you can play every exercise you can unlock in the daily test. In total, there are forty kinds. Some are just adding, subtracting, multiplying or dividing of numbers with 1, 2 or 3 figures. Others let you see the numbers only briefly before you get the chance to write something down. Of course, the nine times tables are also present. Furthermore, you can expect things like fill the blanks and missing numbers. In other words, there's a lot of variation, but in the end it's all the same.

Nintendo states the game is for young ones that have difficulties calculating and older people who want to refresh their maths. Everyone between the age of 12 and let's say 35 will finish this game in an hour or two. For kids younger than twelve, Maths Training is useful but it's the question whether they will like it. In previous games - think of Big Brain Academy - Nintendo proved they are able to make calculating attractive by presenting visual exercises. With Euros or pictures for example. However, they left out that part here so the difference between the game and a number of sums on a piece of paper isn't that big.

That leaves only the older ones. Of course, you need calculating everywhere: doing groceries, cooking for a big group of people out of a book (multiplying the quantity of all the ingredients),... But even for these non-gamers, it would have been pleasant to have exercises with money in it or something like that.
