Students learn how to find the perimeter and area of various 2D shapes including triangles, quadrilaterals, compound shapes and circles. Throughout the topic links are made to algebraic reasoning and estimation. This topic takes place in Term 4 of Year 9 and links to arc length and area of sectors later on.
know and apply formulae to calculate:
calculate the perimeters of 2D shapes, including composite shapes;
Students are challenged to apply their understanding of the mean, mode, median and range to calculate datasets by setting up and solving equations.
Five, real-life and functional problem solving questions on compound percentage changes.
Home learning project teaching how to create pull up nets for 3D shapes.
