Y10 Foundation: Topic 11: Perimeter and area

Objectives:

    • Find the perimeters and areas of shapes made up from triangles and rectangles
    • Find areas of shapes by counting squares
    • Derive and use formulae to find the area of shapes made up of rectangles and triangles
    • Find the surface area of cuboids and prisms
    • Solve a range of problems involving areas
    • Convert between units of area

Prior Knowledge:

    • Names of triangles, quadrilaterals and polygons
    • Knowledge of the properties of rectangles, parallelograms and triangles
    • Concept of perimeter and area
    • Units of measurement
    • Four operations of number

Key Vocabulary:

  • Copy and paste here.

Differentiation & Extension:

    • Calculating areas and volumes using formulae
    • Using compound shape methods to investigate areas of other standard shapes such as a trapezium or a kite
    • Practical activities, eg using estimation and accurate measuring to calculate perimeters and areas of classroom/corridor floors

Using & Applying ideas:

  • Collaborate here.

NOTES
    • Discuss the correct use of language and units
    • Ensure that students can distinguish between perimeter, area and volume
    • Many students have little real understanding of perimeter, area and volume. Practical experience is essential to clarify these concepts
