《MathStart》系列為美國HarperCollins出版的暢銷數學啟蒙書。作者Stuart J. Murphy認為數學與日常生活息息相關，他為了建立小朋友基礎的數學概念與知識，讓小朋友輕鬆愉快地學習數學，因而精心設計了這套生活化的《MathStart》數學啟蒙繪本，從生活話題與情境故事，讓小朋友有效地吸收數學概念。 全系列分為三個Level，Level 2 開始接觸數字的運用與計算。 《A Fair Bear Share》講述熊媽媽叫所有的熊小朋友去搜習材料回來做藍莓批，回來後就以10為一組計算各材料的數目。學習《Group of tens》是加數的基本概念。 書內還會介紹不同的遊戲讓小朋友強化《減數》的概念。 Mama Bear wants to make her special Blue Ribbon Blueberry Pie, but it's up to her four cubs to gather enough nuts, berries and seeds. Three of the cubs go at it with gusto, adding up their treasures by arranging them in groups of tens and ones. But they don't have enough! Will their little sister—the one who spent the afternoon skipping, running and turning cartwheels—come through and save the day? Learning how to regroup numbers is essential for solving more advanced addition problems. Paperback / For Ages: 4-7 / 40 pages
