Imagine your class is decorating the old art room for a school play set. You need to know exactly how much paint, carpet, or wallpaper to buy. Too little and the job's unfinished. Too much and you've wasted money.

Today you'll measure a real space in your school: a classroom, a yard, a stage area: using a tape measure. You'll convert between cm and m, calculate the perimeter (edge distance) and area (floor space), and record it all for your project budget.

Every real project starts with accurate measurements. Here's what you'll master today, with a worked classroom example.

Now measure your actual project space: the room, yard, or stage area for your class project. Work in groups of 3: one holds the tape, one calls the measurement, one records.

Steps:

1. Choose your space (art room, yard corner, drama stage).
2. Measure length and width to the nearest cm using the class tape measures.
3. Convert cm to m (divide by 100).
4. Calculate perimeter: 2 × (length + width).
5. Calculate area: length × width.
6. Sketch a quick outline with dimensions labelled.

Record everything in the worksheet next: this feeds your KA1 evidence directly.

Transfer your group's measurements here. This is your portfolio artifact for MA1 KA1: 'Collecting, Comparing and Calculating' evidence. Save as LCA_Maths_Portfolio/03_space_measurements_v1.docx.

Success criteria: All measurements shown in m to 2 decimal places; perimeter uses 2×(L+W) formula shown; area uses L×W formula shown; sketch includes scale and labels.

Discuss with your group:

• What was hardest: measuring straight, converting units, or calculating?
• How does 1 cm error affect paint or carpet cost?
