Students use diagrams of two boxes with given dimensions to calculate the volume of both boxes and the number of smaller boxes that could fit into one of the boxes.
This practical task requires students to construct a one metre newspaper roll, use it to estimate the dimensions of a room, then calculate the volume of that room.
Students calculate the height of two cylinders given the radius, and identify a correct general statement about the relationship between radius and height for a given volume.
This practical task has students investigate the surface area of three objects and whether this influences the rate of evaporation. Students fill in a table, and calculate the water loss and answer questions to show their understanding.
Students write the simplest algebraic expressions for the lengths and area of parts of a composite shape, then solve these expressions using substitution. They then solve an equation that relates an algebraic expression to a given side length.
