Area of Triangles & Parallelograms
Calculate the area of parallelograms and triangles using formulae (A = b × h for parallelograms, A = ½ × b × h for triangles)
Suggested ages 10–11
Learning journey
Your child is mastering advanced measurement skills — calculating volume and area using formulas, converting between different units of measurement, and solving real-world problems involving length, mass, and capacity.
Evidence of understanding
- Calculate the area of a parallelogram with base 8 cm and height 5 cm
- Calculate the area of a triangle with base 12 cm and height 7 cm
- Explain why the area of a triangle is half the area of a related parallelogram
Assessment prompt
If Area of Triangles & Parallelograms is cutting triangular pieces of cloth where the base is 8 cm and the height is 5 cm, can they use a formula to work out the area of each piece?
