Why do so any children run and hide from multiplications and decimal numbers? Perhaps because they haven't yet found out just how much fun there is to be had in math ... In particular, with these two new books in the series Mad for Math, children will find out that math problems can be surprisingly fun when done with the entertaining monsters from the planet Zot, and that fractions are completely different when you learn them together with a band of pirates and Greg the parrot! Thanks to the brightly coloured and exciting places, young readers will have to help the characters to solve enigmas and problems with mathematical calculations. The journeys are structured in a gradual and intuitive way: the main aim of these innovative activity books is, in fact, to help children learn independently, encouraging them to use their brains to understand the mathematical rules while playing. This is why there are no definitions or abstract formulas in these books. Children can however check their answers against the solutions found at the back of the books. This series of didactic and educational books will teach children that not only can you play with math ... you can even have fun! Ages: 10 plus
