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 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.

Each interval on this {{}} is 0.1 as there is a difference of 1 unit over 10 intervals. The arrow is pointing at 35.6.

The arrow on this scale is pointing at {{ }}.

1 cup is equivalent to 16 tablespoons. Match each quantity to its equivalent quantity.

12 tablespoons are equivalent to 1.5 sticks. This means that 1 stick is equivalent to {{ }} tablespoons.

Approximately 28 grams are equivalent to 1 ounce (oz). There are 16 ounces in a pound. The arrow on this scale is pointing at approximately {{ }} kilograms.

Match each measurement to an equivalent measurement.

This ratio table shows that $$a$$ = {{ }}.

Lucas uses 450 g self-raising flour to make a sponge. Lucas should use {{ }} eggs for his sponge.

Aisha uses 2.5 lemons to make a sponge. Aisha should use {{ }} tsp of vanilla extract for her sponge.

Using 1 ft = 12 in and 3 ft ≈ 1 yd means 6 yd ≈ {{ }} in.
