Students learn how to find the area of various 2D shapes parallelograms, trapezia, compound shapes and circles. Throughout the topic links are made to algebraic reasoning and estimation. This topic takes place in Term 1 of Year 9 and links to volume and surface area later on.
In this lesson, we learn about the length and volume scale factor of 3D shapes and the relationship between them.
How to solve simultaneous equations using the substitution method.
How to compare datasets using box and whisker diagrams.
