This series aims to encourage a positive attitude towards maths and numbers through a play-based learning approach. For each theme there is both an activity book and a game box, which can be purchased and used independently.The activity book is intended for use by children on their own, while the game box will enable them to challenge one or more of their friends. Each of the activity books tell a story, intended to stimulate the child's curiosity and motivation. The mathematical topics are introduced gradually and intuitively. The game boxes have the same style and contents as the corresponding activity books, but can be used completely independently of the books. The box also includes an instruction booklet and notes for parents and teachers.
