Gunakan kumpulan sama banyak dan tanya jumlah keseluruhan.
Langkah 1
Cerita darab
Gunakan kumpulan sama banyak dan tanya jumlah keseluruhan.
kumpulan × setiap kumpulan = jumlah
Cerita darab = 乘法故事 编乘法故事要有“几组”和“每组一样多”，最后问一共有多少。故事里的组数和每组数量对应算式里的两个数。常用的词有“每个”“各有”“一共”。 例子：3 × 5 = 15：有 3 个篮子，每个篮子装 5 个橙，一共有几个橙？3 × 5 = 15 个。 注意：一定要说明每组数量相同，否则不能用乘法。
Cerita darab = Multiplication story A multiplication story needs a number of groups with the same amount in each, and it asks for the total. The groups and the amount in each group match the two numbers in the sentence. Words like 'each' help. Example: 3 × 5 = 15: there are 3 baskets with 5 oranges in each basket. How many oranges altogether? 3 × 5 = 15 oranges. Watch out: Say that every group has the same amount.
Langkah 2
Cerita bahagi
Gunakan jumlah yang dikongsi atau dikumpul sama banyak dan tanya jawapan bahagi.
jumlah ÷ kumpulan = setiap kumpulan
Cerita bahagi = 除法故事 除法故事从一个总数开始，把它平均分给几组，或每几个分成一组。然后问每组几个，或能分几组。故事里一定要有“平均”或“一样多”的意思。 例子：20 ÷ 4 = 5：20 块饼干平均放进 4 个盒子，每盒几块？每盒 5 块。 注意：总数要放在故事开头，并且是故事里最大的数。
Cerita bahagi = Division story A division story starts with a total that is shared equally or put into equal groups. It then asks how many are in each group or how many groups there are. The words 'equally' or 'the same' must be in the story. Example: 20 ÷ 4 = 5: 20 biscuits are put equally into 4 boxes. How many in each box? 5 biscuits. Watch out: The total belongs at the start of the story, and it is the biggest number.
Langkah 3
Masukkan baki jika perlu
Jika pembahagian tidak tepat, cerita mesti menerangkan objek yang berbaki.
Masukkan baki = Include the remainder If the sharing does not come out exactly, the story must say how many are left. Total = complete groups + remainder, so the ending tells both the groups and the leftover. So readers know not everything was shared. Example: 17 ÷ 5 = 3 remainder 2: 17 stickers, 5 for each child, are enough for 3 children with 2 left over. Watch out: The leftover must be fewer than one share.

Cerita darab sepadan = Matching multiplication story The question asks which story fits 6 × 4 = 24. It needs equal groups and a total at the end. In each story, look for 'each one has' and check what the ending gives. Example: 5 × 2 = 10: 5 pairs of shoes with 2 shoes in each pair make 10 shoes. Watch out: Check the job of each number: groups, amount in each, or total.

Cerita bahagi sepadan = Matching division story The question asks which story fits 27 ÷ 3 = 9. A division story shares a total equally and tells each share. For every story, ask: which number is the total, is it shared equally, and what does the last number describe? Example: 16 ÷ 2 = 8: 16 pencils shared equally into 2 cases gives 8 in each. Watch out: Circle the total first; it should match the number before the division sign.
