📏 Part 1: Quick Choices

1. Which tool is best to measure the length of a desk to the nearest millimetre?

Ruler (with mm scale)

Kitchen scales

Stopwatch

Thermometer

2. Which unit is most appropriate to record the thickness of a pencil?

kilometres (km)

metres (m)

centimetres (cm)

millimetres (mm)

3. Which shows an area unit?

m

cm²

L

kg

4. Check all that help improve measurement accuracy:

Start measuring from the zero mark on the ruler

Measure while the ruler is tilted at an angle

Measure twice and compare results

Use the correct unit for the size of the object

✏️ Part 2: Calculations and Records

5. Conversion: A pencil is 17.6 cm long. Convert this length to millimetres (mm).

6. Perimeter: A rectangle on the Perimeter Station measures 12 cm by 8 cm. Calculate its perimeter.

7. Area: On the Area Station a rectangle covers 7 squares by 5 squares on 1 cm² grid paper. What is the area in cm²?

8. Volume: A rectangular box used at the Volume Station measures 10 cm × 4 cm × 3 cm. Find the volume in cubic centimetres (cm³) and convert to litres (L). (1000 cm³ = 1 L)

🧠 Part 3: Match & Reflect

9. Match each measurement type with the best unit. Draw a line between the columns.

A. Length

B. Area

C. Volume

D. Mass

1. cm³

2. m

3. kg

4. cm²

10. Short reflection: Which station did you find easiest and which was hardest? Write one strategy you used (or will use) to check accuracy at stations.

11. Draw and label: In the drawing box sketch a rectangle you might measure at a station. Label two sides with lengths (cm) and write its area and perimeter below.
