Arranged in colour-coded levels, this high-interest range will appeal to children of varying ages and abilities. The exciting titles use the maths skills learnt in the classroom in real-life puzzle-solving scenarios, helping readers to develop an appreciation of the wider relevance of mathematics. In Zoo Keeper for the Day, readers can solve puzzles that show how much food Zebras eat, the weight of a baby Kangaroo and how much poo each animal produces (yuk!) and many more.
