「組合達人」讓小朋友掌握 2-18 各數的組成，通過有趣的互動遊戲，強化小朋友的心算能力和數字感，是日後速算加法的重要基礎。
Number Maker takes a novel approach to children’s mathematical education via the composition of numbers between 2 and 18, working with children instead of forcing them to work on dull, repetitive exercises. Through a fun-filled approach to learning, it builds up sensitivity to numbers as well as an intuitive understanding of arithmetical relations.
