For ages 9-12. Maths, history, art, and world cultures come together in this delightful book for kids, even for those who find traditional maths lessons boring. More than 70 games, puzzles, and projects encourage kids to hone their maths skills as they calculate, measure, and solve problems. The games span the globe, and many have been played for thousands of years, such as three-in-a-row games like Achi from Ghana or the forbidden game of Jirig from Mongolia. Also included are imaginative board games like Lambs and Tigers from India and the Little Goat Game from Sudan, or bead and string puzzles from China, and Mobius strip puzzles from Germany. Through compelling maths play, children will gain confidence and have fun as they learn about the different ways people around the world measure, count, and use patterns and symmetry in their everyday lives.
