Year 5 MEASUREMENT:

Solve practical problems involving the perimeter and area of regular and irregular shapes.

Year 6 MEASUREMENT:

Use the formula for the area of a rectangle and angle properties to solve problems.

• Year 6: Discuss real-world uses of perimeter and area (e.g., fencing a garden, flooring a room).

Explicit Teaching:

• Introduce formulas:

  • Perimeter = 2 × (length + width)

  • Area = length × width
    
    

Year 5: Directly apply formulas to simple problems.

Year 6: Work with missing values (e.g., "If the area is 24m² and one side is 6m, what is the missing side?").

Measure the Carpark
Go outside and have students measure the car park as a class. Have discussions about possible estimations- decide on a class estimate. 

Record the measurements.

Draw a Floor Plan:
On graph paper, students draw a scaled version of the carpark using the measurements they collected.

Calculate Area and Perimeter:
the formulas, students calculate the area and perimeter of the carpark or sections they measured.

Reflection
Work out the difference between the class estimation and actual measurements.

Warm-up:
Present a real-world scenario (e.g., “How much carpet is needed for a rectangular room?”).

Mini Lesson
Year 5: Teach students how to split an L-shape into two rectangles and add their areas. Work through one composite shape as a class.

Year 6: Include missing side lengths (e.g., one side is missing, use subtraction to find it). Solve a real-world problem (e.g., “Find the area of an irregular garden bed”).

Independent
Students complete differentiated composite shapes activity

Extension: Create their own irregular shape and find its area. 

Reflection
What do you do when a shape is not a perfect rectangle?

How does finding a missing side help in solving area problems?

Mini Lesson
Ask: "Have you ever been to a playground? What makes a playground fun and useful?"

Discuss different playground features (e.g., slides, swings, sandpits, paths, seating areas).

Show examples of real playground layouts (simple for Year 5, more complex for Year 6).

Today, we will design our own playgrounds and calculate the area and perimeter to ensure our spaces are functional and well-measured!"

Recap Perimeter & Area Formulas:

• Perimeter = Add all sides (P = 2 × (length + width) for rectangles)

• Area of a rectangle = length × width

👀 Demonstration (Whole Class Example):

1. Draw a simple playground design (e.g., a rectangular playground measuring 10m × 6m).

2. Calculate the perimeter: P = 2 × (10 + 6) = 32m

3. Calculate the area: A = 10 × 6 = 60m²

4. Discuss why these measurements matter for real-world design (e.g., knowing how much space you have for equipment).

Independent
Year 5:

• Design a simple rectangular playground.

• Include at least two features (e.g., swing set, sandpit).

• Calculate and label the area and perimeter.

Year 6:

• Design a multi-section playground using at least two different shapes (e.g., rectangles + triangles or trapeziums).

• Include at least three features (e.g., slide, climbing area, seating space).

• Use angles and missing side properties to calculate total area/perimeter.

👀 Teacher Support:

• Walk around and assist students in applying formulas correctly.

• Encourage accuracy and creativity (e.g., ensuring realistic sizes for play areas).

Students will create an A3

Reflection
Select a few students to present their playgrounds and explain how they calculated their area and perimeter.
