Here's a game with a simple concept: 110 cards each including multiplying two numbers taken from the tables of 0-10, with the result back. Personally, I have used it twice:
_ With a primary school child. The appearance set aside, remains the only intellectual challenge. We pass the 110 cards reviewed, discarding each time non-addition products. On error, think about taking a few seconds to read aloud once the calculation and its result, to solicit visual and auditory memories. I was amazed by the commitment and motivation of a student EC1, yet reluctant to learning and the general effort.
_ For very strong in math, I offer this: have nine square cards face operation and then randomly select a number between 50 and 100 (college calculators do this very well) and try to determine what cards allow you to achieve these, the addition or subtraction of the results of the cards. Both say that you drool, but it's good for both the Brain Gym and modesty.
The instructions supplied with the cards offers other possible uses that I have not tried, and it is likely that everyone will find his account. It is reassuring, in 2011, to see that this type of game, simple and demanding, can still compete with sophisticated machinery which is expected any.
