商品描述媒体推荐Free of the tediousness of writing while teaching children efficient methods of solving math problems, this guide reintroduces the concept of verbal, or mental, math in a step-by-step fashion. Removing the drudgery and turning math into a game, it uses a time-honored approach to help children become proficient with fractions and percents. Fractions and decimal operations, after the four basic arithmetic operations, are the most fundamental of math concepts, and future progress in math will depend on how well a child understands these concepts.
