Students calculate the size of marked angles using their knowledge of angle properties: the angle between a tangent and a radius, the sum of angles in a triangle and the sum of angles in a quadrilateral.
Task: Students make predictions about evaporation rates of instances where surface areas are a factor, select which variable is being investigated in both examples and explain their answer. Assessment focus: Using knowledge of surface area to make predictions.
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.
