Metric units are based around the standard units of metre, gram and litre.

Imperial is a system of units for measuring, which was created in the early 1800s, during the British Empire.

An interval is the space between two values or points. On a scale, intervals are shown using a small mark or line to show the space between.

Problem solving with complex 2D shapes

In this unit, pupils built upon their prior learning of the area of different shapes. In the future unit, pupils will continue to further develop their understanding of shapes by considering surface area and volume of pyramids, spheres and cones.

In the prior unit, pupils derived the formula for the circumference and area of a circle. In this unit, this knowledge is combined with knowledge of fractions to find the arc length and area of a sector.

In this unit, knowledge of circles and polygons is drawn upon to find the arc length and area of a circle sector and areas of complex compound shapes.
