Kelab Sukan memberi beberapa petunjuk tentang ahlinya.
Bolehkah kamu mencari bilangan ahli setiap permainan, kemudian melukis carta palang?

Akal Pintar
用线索推数据 = cari data daripada petunjuk 这道动脑题没有直接给出每一项的人数,只给了总人数和几条线索。我们要像侦探一样,一条一条用线索,推出每一项的人数,再把它们画成条形图,最后从图里说出资讯。 例子:两个班一共 70 人,甲班 40 人,乙班就是 30 人。 注意:推出来以后,把全部人数加起来,要等于总人数。
finding data from clues = cari data daripada petunjuk This puzzle does not give the number for each item directly; it gives only the total and a few clues. Like a detective, use the clues one at a time to work out each number, draw them as a bar chart, and then state information from the chart. Example: two classes have 70 pupils altogether; if one has 40, the other has 30. Watch out: when you finish, the numbers must add up to the total.

Yang sudah diketahui: jumlah 60, bola sepak 20

① Kelab Sukan ada 60 orang ahli dalam 4 permainan.
② 20 orang bermain bola sepak.
③ Ahli badminton sama dengan ahli sepak takraw.
④ Ahli hoki 4 orang lebih daripada ahli badminton.
先读全部线索 = baca semua petunjuk 四条线索里,有两条是直接的数字:总数 60 人,足球 20 人。另外两条是关系:羽毛球和藤球一样多;曲棍球比羽毛球多 4 人。先处理直接的数字,再用关系来推。 例子:“A 和 B 一样多”表示两者的数字相同。 注意:“多 4 人”是加 4,不是乘 4。
read every clue first = baca semua petunjuk Of the four clues, two give numbers directly: 60 members in total and 20 who play football. The other two are relationships: badminton equals sepak takraw, and hockey has 4 more than badminton. Use the direct numbers first, then the relationships. Example: 'A is the same as B' means the two numbers are equal. Watch out: '4 more' means add 4, not multiply by 4.

badminton = takraw = 12 · hoki = 16

40
Badm.
Takraw
Hoki
+4
60 − 20 = 40 · 40 − 4 = 36 · 36 ÷ 3 = 12
Badminton 12 · Takraw 12 · Hoki 12 + 4 = 16
一步一步推 = cari langkah demi langkah 先从总数减去足球:60 − 20 = 40,这 40 人是羽毛球、藤球和曲棍球。画条形模型:三个一样长的格子,曲棍球多出一小段 4。先把多出的 4 拿掉:40 − 4 = 36,剩下三个一样的格子,每格 36 ÷ 3 = 12。所以羽毛球 12,藤球 12,曲棍球 12 + 4 = 16。 例子:三项一共 25,其中一项多 1,其余一样:(25 − 1) ÷ 3 = 8。 注意:最后检查:20 + 12 + 12 + 16 = 60。
working it out step by step = cari langkah demi langkah First take football away from the total: 60 − 20 = 40, the members of badminton, sepak takraw and hockey. Draw a bar model: three equal boxes, with hockey having an extra 4. Remove the extra 4: 40 − 4 = 36, leaving three equal boxes of 36 ÷ 3 = 12. So badminton is 12, sepak takraw 12, and hockey 12 + 4 = 16. Example: three items total 25 and one has 1 extra while the others are equal: (25 − 1) ÷ 3 = 8. Watch out: check at the end: 20 + 12 + 12 + 16 = 60.

• Bola sepak paling ramai.
• Badminton dan sepak takraw sama banyak.
• Hoki 4 orang lebih daripada badminton.
画图并写资讯 = lukis dan tafsir 把推出的四个数画成条形图,刻度每格 4,从 0 画到 20。画好后,从图里写出三项资讯:哪一项最多?哪两项一样多?哪一项比哪一项多几人?用完整的句子写。 例子:“藤球比足球少 8 人。” 注意:写的资讯要和图里的数字对得上。
draw and interpret = lukis dan tafsir Draw the four numbers as a bar chart with steps of 4 from 0 to 20. Then write three pieces of information from the chart: which is the most, which two are equal, and which has how many more than another. Write complete sentences. Example: 'Sepak takraw has 8 fewer members than football.' Watch out: every statement must match the numbers in the chart.

Berapakah ahli hoki?

曲棍球的人数 = ahli hoki 先用线索推出羽毛球的人数,再按线索四“多 4 人”加上去。 例子:如果羽毛球是 10,多 4 人就是 14。 注意:可以把四项加起来检查是不是等于 60。
the hockey members = ahli hoki First use the clues to find the badminton number, then add the 4 extra from clue 4. Example: if badminton were 10, 4 more would be 14. Watch out: you can add all four to check they make 60.

47 orang murid memilih warna kegemaran: merah, biru atau hijau. 15 orang memilih merah. Biru 4 orang lebih daripada hijau. Berapakah murid yang memilih biru?

两项相差几人的推理 = beza dua kumpulan 先从总数减去已知的那一项,剩下的是另外两项的总和。这两项中,一项比另一项多 4 人:先拿掉多出的 4,剩下的平分成两份,就是比较少的那一项;再加 4,就是比较多的那一项。 例子:两项一共 20,一项多 2:(20 − 2) ÷ 2 = 9,另一项 11。 注意:题目问的是比较多的那一项还是比较少的那一项?
two groups that differ = beza dua kumpulan Subtract the known group from the total; what is left is the other two groups together. One of them has 4 more than the other: remove the extra 4, split the rest into two equal parts for the smaller group, then add 4 for the bigger group. Example: two groups total 20 and one has 2 more: (20 − 2) ÷ 2 = 9, so the other is 11. Watch out: does the question ask for the bigger group or the smaller one?

Maklumat manakah betul berdasarkan carta?

检查资讯 = semak maklumat 先读出每个长条的数值,再一句一句检查:说“最多”的,看是不是最高的长条;说“多几人”的,用减法算一算对不对;说“一样多”的,要看两个长条是不是一样高。 例子:两个长条一个停在 12、一个停在 16,就不是一样多。 注意:每一句都要检查,不要只看第一句。
checking statements = semak maklumat Read the value of each bar, then check each sentence: for 'the most', see if it is the tallest bar; for 'how many more', work out the subtraction; for 'the same', see whether the two bars are equally tall. Example: bars ending at 12 and 16 are not the same. Watch out: check every sentence, not just the first.
