Uses the comparative size of familiar objects to make reasonable estimations of length, mass, area and capacity.
Estimates to the nearest appropriate unit, then measures accurately: length, height and distance in millimetres (mm), centimetres (cm), metres (m) and kilometres (km); mass in grams (g) and kilograms (kg); and capacity in millilitres (ml) and litres (l).
Calculates the perimeter of simple straight sided 2D shapes in millimetres (mm), centimetres (cm) and metres (m).
Calculates the area of squares, rectangles and right-angled triangles in square millimetres (mm2), square centimetres (cm2) and square metres (m2).
Calculates the volume of cubes and cuboids in cubic centimetres (cm3) and cubic metres (m3).
Converts between common units of measurement using decimal notation, for example, 550 cm = 5·5 m; 3·009 kg = 3009 g.
Chooses the most appropriate measuring device for a given task and carries out the required calculation, recording results in the correct unit.
Reads a variety of scales accurately.
Draws squares and rectangles accurately with a given perimeter or area.
Demonstrates understanding of the conservation of measurement, for example, draw three different rectangles each with an area of 24 cm2.
Shows awareness of imperial units used in everyday life, for example, miles or stones.
