📏 Part 1: Measurement Practice

1. What is the most appropriate unit to measure the length of your classroom?

millimetres (mm)

centimetres (cm)

metres (m)

kilometres (km)

2. Convert these measurements:

a) 250 cm = _______ m

b) 1.5 m = _______ cm

c) 3200 mm = _______ m

3. Before measuring, estimate the length and width of your desk:

Estimated length: _______ cm Estimated width: _______ cm

Now measure and record the actual dimensions:

Actual length: _______ cm Actual width: _______ cm

Calculate the area of your desk: _______ cm²

4. Which tools would be best for measuring these spaces? Draw lines to match:

Width of a pencil

Length of classroom

Height of a book

School playground

30cm ruler

Measuring tape

30cm ruler

Measuring tape

📐 Part 2: Area Calculations

5. Calculate the area of a rectangular garden bed that measures 4.5m long and 2.8m wide:

Area = _______ m²

6. A composite shape consists of two rectangles joined together:

Rectangle A: 6m × 3m

Rectangle B: 4m × 2m

Total area = _______ m²

7. Group Measurement Task - Record your group's measurements:

Object/Space measured: _________________________

Length: _______ cm Width: _______ cm

Calculated area: _______ cm²

What challenges did your group face while measuring?

🏙️ Part 3: Connecting to Urban Design

8. Why is accurate measurement important in urban planning? Choose all that apply:

To ensure buildings fit properly on sites

To calculate how much green space is available

To determine construction costs

To plan efficient transport routes

9. A sustainable neighbourhood needs 20% of its total area to be green space. If the neighbourhood covers 50,000 m², how much green space is required?

Required green space = _______ m²

10. Reflection: How will the measurement skills you practised today help you in designing your sustainable neighbourhood project?

11. Challenge: If you were designing a playground that measures 15m × 20m on your plan, but the scale is 1:50, what would the real-world dimensions be?

Real length: _______ m Real width: _______ m
