啟發孩子對數的概念與對算術的興趣，
歡樂邁出「數學的第一步」，長大後更有解決數學題目的能力。

讀者讚譽
這本書是為即將入學的大女兒買的，她一直說不喜歡算術，卻非常喜歡閱讀，這本書應該可以提高她的學習興致吧！這個冒險故事中，小朋友必須算出各式各樣小東西和小動物的數量，在趣味中接觸數學。看到一半，連牙牙學語的小女兒也加入了，姊姊開始帶著妹妹一起數，看到女兒們這麼熱衷於算術，真的很欣慰。──日本．小樹媽媽
我數學不好，也一直不曉得如何培養孩子的數學觀念，所以朋友推薦我這本「新生必備的數學繪本」。透過超人與外星人的故事，讓孩子數數、加總全部的數量等等，非常寓教於樂，還附上數學家寫給家長的解說，有很多值得參考的地方。書中以5當作基準，用「比5多3」這種分解、合成的概念去解釋8這個數字，有助於讓孩子打下扎實的基礎。──日本．真央倫
七歲的女兒吵著要買這本書，原本覺得內容對她來說太簡單了，但看到她專注的向四歲弟弟說明算術的方法時，覺得這本書真是買對了！閱讀的過程就像在學數學，姊弟倆一邊朗讀一邊計算，很開心的樣子。期待每個人都能夠放下「數學很困難」的想法，在趣味中學習。──日本．Cucina
