bekas berlainan = different containers Gather a few different containers, such as cups, a bottle and a jug. Choose ones that will not break easily, have a wide mouth and do not spill when you pour. Example: 2 cups, 1 bottle and 1 jug make 2 + 1 + 1 = 4 containers. Watch out: a narrow bottle mouth makes pouring messy, so a funnel can help.
Langkah 2
Anggar dan rekod
Catat anggaran isi padu setiap bekas dalam mℓ atau ℓ.
anggar dan rekod = estimate and record In the table, write how much you think each container holds, using mℓ or ℓ. A small cup suits mℓ, while a big jug can use ℓ. Example: the cup is estimated at 200 mℓ and the bottle looks twice as big, so 200 + 200 = 400 mℓ. Watch out: write every estimate before measuring; one written afterwards is not an estimate at all.
Langkah 3
Sukat dan buat kesimpulan
Sukat isi padu sebenar, kemudian nyatakan bekas yang anggarannya paling hampir.
buat kesimpulan = make a conclusion Measure the real amount in each container, find the gap between estimate and actual, and then name the container whose estimate came closest. Example: cup estimate 200 mℓ, actual 240 mℓ, gap 240 - 200 = 40 mℓ; jug estimate 2 ℓ, actual 2 ℓ, gap 2 - 2 = 0 ℓ, so the jug estimate is best. Watch out: change to the same unit first, because mℓ and ℓ cannot be compared directly.

urutan aktiviti isi padu = order of the volume activity The question asks for the correct order of the three steps in the liquid activity. Recall what came first, next and last in this lesson. Check that every action is about liquid. Example: washing hands means wet, soap, then rinse, 1 + 1 + 1 = 3 steps, and the wrong order leaves hands dirty. Watch out: all three words must fit; a choice with only one suitable word is not enough.

Bekas sesuai untuk aktiviti perlu…
bekas sesuai = 合适的容器 题目问：活动用的容器要有什么条件。回想 Langkah 1，想想倒水时要避免什么事情发生，例如漏水、洒出来或打破。 例子：容器装 500 mℓ，漏掉 50 mℓ，只剩 500 - 50 = 450 mℓ，量出来就不准。 注意：想想容器有问题时，量出来的数会变成怎样。
bekas sesuai = suitable container This question asks what a container needs for the activity. Recall Langkah 1 and think about what must not happen while pouring, such as leaking, spilling or breaking. Example: a container holding 500 mℓ leaks 50 mℓ, leaving only 500 - 50 = 450 mℓ, so the measurement is wrong. Watch out: imagine how a faulty container would change the number you measure.
