Lessons
6Surface Area and Volume: Rectangular Prisms
Draw the net of a rectangular prism, derive and apply the surface area and volume formulas, and investigate the effect of doubling dimensions.
Surface Area and Volume: Triangular Prisms
Calculate the surface area, volume and capacity of triangular prisms, using the Theorem of Pythagoras for missing dimensions.
Surface Area and Volume: Cylinders
Use the net of a cylinder to calculate surface area, apply the volume formula with the correct order of operations, and solve capacity and painting problems.
Transformations: Translations
Recognise, describe and perform translations of points and figures on the Cartesian plane, within and across the quadrants, using the rule (x; y) to (x + p; y + q).
Transformations: Reflections in the X-axis and Y-axis
Reflect points and figures in the X-axis and Y-axis, using the rules (x; y) to (x; -y) and (x; y) to (-x; y), and describe the properties of reflections.
Transformations: Reflection in the Line y = x
Reflect points and figures in the line y = x by interchanging coordinates, using the rule (x; y) to (y; x), and identify transformations from object-image pairs.
