Included Skills: Geometry
Measurement • I can use my knowledge of the sizes of familiar objects or places to assist me when making an estimate of measure. • I can use the common units of measure, convert between related units of the metric system and carry out calculations when solving problems. • I can explain how different methods can be used to find the perimeter and area of a simple 2D shape or volume of a simple 3D object. • 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.
