Much of the learning was done within the context of the following Units.Unit 10: Circumference and Area of a CircleThis Unit introduced you to the value of pi; the ratio of a circle’s circumference to its diameter. You used this to calculate the area and perimeter of circles, as well as consolidating your understanding of the area and perimeter of other shapes.Unit 11: 3D shapes and netsIn this Unit you investigated the properties of 3D shapes. You learned to identify and create nets of 3D shapes, and build them using blocks.Unit 12: Surface Area and Volume of 3D shapesThis Unit applied your understanding of 3D shapes to finding the Surface Area and Volume of cubes, cuboids and other prisms. You also learnt to convert between measures of Area and Volume, and to use your understanding of Volume to calculate missing lengths.Pre-Learning Assessment Mark:1333500628640050Post-Learning Assessment Mark:1237615628640050Teacher Comment:Find the area of a circle with a radius of 8 m.
