(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.
