加法第8關：加起來超過100怎麼算？算法與解題技巧。［77+88=?］Addition Level 8: How to Add Numbers to Get a Sum Over 100?

加法有一個基本技巧： 「分、合、分、合」 看到無法直接加總算出來的數字，就要開始這個做法 ［1分］，兩位數的加法就是分成十位數跟個位數， ［2合］，把「十位數 跟 十位數 相加，個位數 跟 個位數 相加」 ［3分］，兩個十位數的合大於100，個位數相加大於10，就要繼續分解 a. 三位數分開成為 百位數 與 十位數 b. 十位數分開成為 十位數 與 個位數 ［4合］，再把相同位數的數字加起來，答案就會出現了！ 分開、合起來、分開、合起來，重複這樣的動作，大部分的數學加法，都可以算出來喔！ 補充說明：附上小遊戲連結，可以讓孩子玩兔小紅跟兔小藍搶牧草比賽的遊戲，然後讓他們練習超過100的加法，多練習，數學才會變厲害！以下是兩隻小兔子的Scratch連結 兔小紅：https://scratch.mit.edu/projects/1209... 兔小藍：https://scratch.mit.edu/projects/1209... ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ A Basic Trick for Addition: “Separate, Add, Separate, Add” Whenever you see numbers that are hard to add directly, it’s time to use this method! [Step 1: Separate] For two-digit numbers, break them into tens and ones. [Step 2: Add] Add the tens together, then add the ones together. [Step 3: Separate Again] If the sum of the tens is over 100, or the ones add up to more than 10, Separate again: • Break three-digit numbers into hundreds and tens. • Break tens into tens and ones. [Step 4: Add Again] Add numbers with the same place value. Now the final answer will appear! Just keep repeating: Separate, Add, Separate, Add— With this pattern, most addition problems can be solved easily! Bonus Activity: Practice Addition Over 100 with Two Little Rabbits!
