Reka Cerita

5 × 120 = 600
“Setiap kotak ada 120 biji guli. Ada 5 kotak. Jumlah guli ialah 600 biji.”
912 ÷ 4 = 228
“912 anak benih ditanam sama banyak di 4 petak kebun. Setiap petak ada 228 anak benih.”

Reka Cerita
乘除故事 = cerita darab dan bahagi 乘法故事要有“几组,每组一样多”:5 盒,每盒 120 颗 → 5 × 120。除法故事要有“平均分”:912 棵树苗平均种在 4 块菜地 → 912 ÷ 4。有余数的除法故事,最后还要说剩下多少。 例子:6 × 35 = 210 → 6 辆货车,每辆载 35 箱榴莲,一共 210 箱。 注意:乘法故事是“合起来”,除法故事是“分开来”。
multiplication and division stories = cerita darab dan bahagi A multiplication story has several equal groups: 5 boxes of 120 → 5 × 120. A division story shares equally: 912 seedlings planted equally in 4 garden plots → 912 ÷ 4. A division story with a remainder also says how many are left over. Example: 6 × 35 = 210 → 6 lorries each carry 35 boxes of durian, 210 boxes altogether. Watch out: multiplication stories put groups together; division stories split a total apart.
Pilih cerita

Cerita manakah sesuai dengan 6 × 150 = 900?

乘法故事 = cerita darab 6 × 150 表示 6 组,每组 150:6 个书架,每个书架 150 本书,共 900 本。“借走 150 本”的故事是减法,“再买 6 本”的故事是加法。 例子:4 × 25 = 100 → 4 包,每包 25 颗糖。 注意:乘法故事一定要有“每一个都一样多”。
multiplication story = cerita darab 6 × 150 means 6 groups of 150: 6 shelves with 150 books each, 900 altogether. The story where 150 are borrowed is subtraction, and the one where 6 more are bought is addition. Example: 4 × 25 = 100 → 4 packets of 25 sweets. Watch out: a multiplication story needs every group to be the same size.
Padankan

Ayat matematik dan cerita

算式配故事 = padankan ayat dengan cerita 先看算式是乘还是除。乘法:故事里已经知道“有几组、每组几个”,要求总数;除法:故事里先给一个总数,再把它平均分开。然后核对数字:故事里的数要和算式里的数一样。 例子:“每排 10 张椅子,共 5 排” → 5 × 10;“40 本书平分给 4 组” → 40 ÷ 4。 注意:不能只看关键词,setiap 在乘法和除法故事里都会出现,要看故事是“合起来”还是“分开来”。
match sentence to story = padankan ayat dengan cerita First decide whether the sentence multiplies or divides. A multiplication story gives the number of groups and the size of each group and asks for the total; a division story starts with a total and shares it out. Then check that the numbers in the story match the sentence. Example: '10 chairs in each row, 5 rows' → 5 × 10; '40 books shared by 4 groups' → 40 ÷ 4. Watch out: do not rely on one keyword; setiap can appear in both kinds of story, so ask whether groups are joined or a total is split.
Tulis ayat matematik

2 350 keping kad dimasukkan ke dalam kotak. Setiap kotak diisi 100 keping.

写除法算式 = tulis ayat bahagi 把 2 350 张卡每 100 张装一盒,就是 2 350 ÷ 100。除以 100 时最后两位是余数:23 盒,剩 50 张 → 2 350 ÷ 100 = 23 baki 50。 例子:1 280 ÷ 100 = 12 baki 80 → 12 盒,剩 80 个。 注意:× 卡用不到。
write a division sentence = tulis ayat bahagi Packing 2 350 cards 100 to a box is 2 350 ÷ 100. Dividing by 100, the last two digits are the remainder: 23 boxes with 50 left → 2 350 ÷ 100 = 23 baki 50. Example: 1 280 ÷ 100 = 12 baki 80. Watch out: the × card is not needed.
Lengkapkan cerita

4 × RM125 = RM500
Ayah membeli ① buah kipas. Harga sebuah kipas ②. Ayah membayar ③ semuanya.

补全故事 = lengkapkan cerita 4 × RM125 = RM500:4 是“几台风扇”,RM125 是“一台多少钱”,RM500 是“一共付多少钱”。所以 ① 填 4,② 填 RM125,③ 填 RM500。钱的故事一样用乘法:数量 × 单价 = 总价。 例子:3 × RM20 = RM60 → 买 3 本字典,每本 RM20,一共 RM60。 注意:RM 要写在数字前面,数量(几台)不写 RM。
complete the story = lengkapkan cerita 4 × RM125 = RM500: 4 is how many fans, RM125 is the price of one fan, and RM500 is the total paid. So ① is 4, ② is RM125 and ③ is RM500. Money stories multiply the same way: number of items × price of one = total. Example: 3 × RM20 = RM60 → 3 dictionaries at RM20 each cost RM60. Watch out: RM goes in front of money amounts only, not in front of the number of items.
Lengkapkan cerita

635 ÷ 5 = 127
Kak Yan ada ① biji manggis. Dia membungkus ② biji dalam satu bungkus. Dia mendapat ③ bungkus.

补全除法故事 = lengkapkan cerita bahagi 除法故事从总数开始:一共 635 个山竹(①),每 5 个包一包(②),得到 127 包(③)。被除数是总数,除数是每包几个,商是包数。可以用乘法检查:5 × 127 = 635 ✔。 例子:96 ÷ 8 = 12 → 96 个鸡蛋,每盒 8 个,装成 12 盒。 注意:630 和 12 是多出来的卡,用不到。
complete a division story = lengkapkan cerita bahagi A division story starts with the total: 635 mangosteens (①), packed 5 to a bag (②), making 127 bags (③). The number divided is the total, the divisor is how many in each bag, and the answer is the number of bags. Check: 5 × 127 = 635 ✔. Example: 96 ÷ 8 = 12 → 96 eggs, 8 to a box, fill 12 boxes. Watch out: the cards 630 and 12 are extra and not needed.
