Second - Number, money and measure

Standard 2.NS.1.7 - Compare two figures and find which has the greater perimeter or area.

Included Skills:

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.
