In this practical task students need to weigh books, take measurements of length, convert these as required, and calculate volume and dimensions for a cover.
Students use the angle between a tangent and a radius property and the base angles in an isosceles triangle property to find an unknown angle and to explain why line segments are of equal size.
Students order litre and millilitre capacities from smallest to largest, compare given capacities and explain how they know whether one is larger/smaller or the same.
Students use their knowledge of the trigonometric functions sine, cosine, and tangent to calculate the length of sides of sails in a diagram of a yacht.
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.
In the context of kicking a goal at rugby, students use Pythagoras' theorem to calculate distance. Students then use trigonometry to work out if the kick passes through the posts.
