2、4、6、8、10 — adding 2 five times is 10!
5 個 2 相加就是 10,一起跳著數!
2、4、6、8、10!跳著數(skip counting)是乘法的熱身:「9個2相加是多少?」其實已經是 2×9 的意思,只是還未寫成乘式。遊戲用一籃籃物件,讓小朋友親眼見到「幾個幾」的結構 — 理解先於背誦,乘數表之後才背得有意思、記得牢。
2, 4, 6, 8, 10! Skip counting is the warm-up for multiplication: "nine 2s added together make…?" is already 2×9 in meaning, just not yet written as a multiplication. Counting baskets of objects lets children see the "groups of" structure — understanding before memorising, so times tables stick with meaning.
一起拍手跳數:2、4、6、8… 拍一下說一個,節奏感對記憶幫助很大。見到「9籃、每籃2個」,引導小朋友說出「9個2」— 語言與算式接軌,是乘法概念的關鍵一步。
Clap and skip-count together: 2, 4, 6, 8… one clap per number — rhythm helps memory enormously. Seeing "9 baskets of 2", guide your child to say "nine 2s" — connecting language to the equation is the key step into multiplication.
數筷子(一對對,2個一數)、雞蛋盒(一盒10隻)、紐扣、手指(每人10隻)— 家裡周圍都是「幾個幾」的現成素材,隨時可以玩。
Count chopsticks (pairs — count by 2s), egg cartons (10 a box), buttons, fingers (10 per person) — "groups of" materials are all over the house, ready to play anytime.
