# GCSE/KS3 - Area & Perimeter by Counting

## 3 files23/01/2020

Includes two printable exercises, the solutions of which are in the slides. Only intended for KS3 or Foundation Tier GCSE students.

# Area & Perimeter

## 4 files22/07/2018

(a) Find the perimeter and area of rectilinear shapes.

(b) Find the area of a triangle, trapezium, parallelogram.

(c) Find the area and circumference/perimeter of circles and fractions of circles (e.g. 1/2, 1/4).

(d) Appreciate strategies to find areas of composite shapes, by (i) adding areas (ii) subtracting areas, including appreciation of the 'frame' method and (iii) cutting/reforming areas.

(e) Appreciate that triangles have the same area if their base and height are the same, and compare sizes of triangles by considering the proportion of base/height.

(f) Find what fraction of a shape is shaded by splitting into congruent shapes.# Full Coverage: Area of 2D shapes
