Let’s go step by step through each question.
---
Section 1: Length
1.1 You measure a pencil in centimetres (cm) or millimetres (mm).
→ Pencil is small, so cm or mm makes sense.
1.2 You measure a room in metres (m).
→ Rooms are bigger than pencils, so we use metres.
1.3 You measure the distance you drive in kilometres (km).
→ Driving distances are long, so we use kilometres.

Section 2: Select the correct answer
2.1 Length can be measured in:
a. Gram → that’s for mass
b. Kilogram → also for mass
c. Millilitre → that’s for capacity (liquid volume)
d. Millimetre → YES! That’s a unit of length.
✔ Correct answer:
d. Millimetre

Section 3: Mass
3.1 The scale shows:
Left side: 1 kg
Right side: 400 g + unknown weight
We need to balance the scale → both sides must be equal.
First, convert 1 kg to grams:
1 kg = 1000 g
So:
1000 g = 400 g + ?
→ ? = 1000 - 400 =
600 g
✔ Unknown weight =
600 g

Section 5: Capacity
Look at the milk containers:
A: 1 L
B: 2 L
C: 1 L
D: 5 L
E: 500 mL
Note: 1 L = 1000 mL
5.1 Milk B contains ______ more than milk C
B = 2 L, C = 1 L → 2 - 1 =
1 L
5.2 ______ holders of Milk E is equal to Milk B
Milk E = 500 mL
Milk B = 2 L = 2000 mL
How many 500 mL make 2000 mL?
2000 ÷ 500 =
4
5.3 Milk D contains ______ more liquid than milk A
D = 5 L, A = 1 L → 5 - 1 =
4 L
5.4 ______ millilitre = 1 litre
We know:
1000 millilitre = 1 litre
---
Final Answer:
1.1 cm or mm
1.2 m
1.3 km
2.1 d. Millimetre
3.1 600 g
5.1 1 L
5.2 4
5.3 4 L
5.4 1000
