Selesaikan
Langkah 1

Baca kehendak soalan

Garis kata penting seperti paling besar, susun, bundar atau nombor seterusnya.

baca → tanda
Baca kehendak soalan = 读懂题目要求
解题前先找出题目真正要做什么。把关键词画线,例如 paling besar(最大)、susun(排列)、bundar(四舍五入)。
例子:“用 4、1、7 组成最小的数”,关键词是“最小”,答案是 147。
注意:besar 和 kecil 意思相反,画线时要看清。
Baca kehendak soalan = Read what the question wants
Before solving, find out what the question really asks. Underline key words such as paling besar (biggest), susun (arrange), bundar (round) or nombor seterusnya (next number).
Example: Make the smallest number from 4, 1 and 7. The key word is smallest, so the answer is 147.
Watch out: Paling besar and paling kecil differ by one word, so read closely.
Langkah 2

Pilih strategi

Gunakan jadual nilai tempat, garis nombor atau susunan nombor mengikut kesesuaian.

pilih alat yang sesuai
Pilih strategi = 选择方法
不同的题用不同的工具:比较或组数用数位表,四舍五入用数线,找规律就把数排成一列算间隔。
例子:问 386 到百是多少,用数线:386 在 300 和 400 之间,离 400 比较近,得 400。
注意:别每题都用同一种方法,先想哪种工具最适合。
Pilih strategi = Choose a strategy
Different questions need different tools. Use a place value table to compare or build numbers, a number line to round, and a list of numbers to find a jump.
Example: To round 386 to the nearest hundred, use a number line: 386 lies between 300 and 400 and is closer to 400.
Watch out: Do not use the same tool for every question; pick the one that fits.
Langkah 3

Semak jawapan

Baca semula cerita dan pastikan jawapan menjawab soalan dengan munasabah.

jawab → semak
Semak jawapan = 检查答案
算出答案后,再读一次题目,问自己:答案有没有回答题目?合理吗?
例子:门牌 205、210、215 的下一间,算出 220;检查 220 − 215 = 5,和间隔一样,合理。
注意:答案要放回题目里检查,别算完就停。
Semak jawapan = Check the answer
After finding an answer, read the story again and ask: does my answer really answer the question, and does it make sense?
Example: Doors are numbered 205, 210, 215, and you get 220 for the next one. Check: 220 − 215 = 5, the same jump, so it makes sense.
Watch out: Do not stop after calculating; always check against the story.

Tiga kad digit ialah 2, 5 dan 8. Nombor terbesar ialah…

Nombor terbesar = 最大的数
这题用 2、5、8 三张卡组成最大的数。要让数最大,最大的数字放百位,次大的放十位,最小的放个位。排好后和选项比一比。
例子:用 3、9、6 组成最大的数是 963。
注意:每张卡只能用一次,组成的一定是三位数。
Nombor terbesar = Biggest number
The question uses the digit cards 2, 5 and 8 to make the biggest number. Put the biggest digit in the hundreds, the next in the tens and the smallest in the ones, then compare with the choices.
Example: With 3, 9 and 6, the biggest number is 963.
Watch out: Each card is used once, so the number must have three digits.

Rumah bernombor 410, 420, 430. Nombor rumah seterusnya ialah…

Nombor rumah seterusnya = 下一间的门牌
门牌是 410、420、430,要找下一间。先找间隔:420 − 410 = 10,再用 430 加上间隔。
例子:门牌 155、160、165,下一间是 165 + 5 = 170。
注意:这些门牌每次跳十,不是跳一,别只把个位加 1。
Nombor rumah seterusnya = Next house number
The houses are numbered 410, 420, 430, and you need the next one. Find the jump first: 420 − 410 = 10, then add it to 430.
Example: Houses 155, 160, 165, so the next one is 165 + 5 = 170.
Watch out: These house numbers jump by tens, not by ones.
