In this practical task, students use a coloured spinner and record the frequency of colours occurring. They then use their findings to record the probability of each event and interpret these.
Students draw the next two triangles in a spatial pattern, calculate the areas of a range of triangles, work out the height of a triangle given its area, and write a rule for the pattern.
A spatial pattern involving the area of a shape is represented by a table and a diagram. Students describe the rule in words and as an algebraic expression.
Students calculate the lengths of circles and straight lines on an oval athletics track from its given radius and total length, and show their working.
This practical task requires students to lift a 1 kg weight and then estimate whether a range of everyday objects weigh less than, about the same as, or more than 1 kilogram.
