Primary 2 - Measurement and Geometry

Standard 2.MD.1 - Compare different objects and determine which is heavier or lighter.

Included Skills:

Length, Mass and Volume
• 1.1 measuring
- length in metres/centimetres
- mass in kilograms/grams
- volume of liquid in litres
• 1.2 measuring and drawing a line segment to the nearest cm
• 1.3 using appropriate units of measurement and their abbreviations cm, m, g, kg, l
• 1.4 comparing and ordering
- lengths
- masses
- volumes
• 1.5 solving word problems involving length/mass/ volume
• 1.6 recognise that the term 'weight' is commonly used to mean mass in everyday situations.
• 1.7 compare masses of objects using balance scales.
• 1.8 use everyday examples to develop a sense of
- how long 1 m/1 cm is, e.g. using a metre ruler, width of a fingernail.
- how heavy 1 kg/1 g is, e.g. using a packet of sugar/flour/ rice, a pin, a piece of paper.
- how much 1 litre of liquid is, e.g. using a bottle of mineral water/cooking oil, and 1-litre containers in different shapes.
• 1.9 use their arm span to show 1 m and estimate length in metres.
• 1.10 work in groups to measure the length of curves using a string.
• 1.11 work in groups to measure length/mass using appropriate units and explain their choices of units and how the measurement is done, e.g. measure the length of a longer object in metres and the mass of a heavier object in kg.
• 1.12 estimate length/mass/volume before measuring it and use the word 'about' (e.g. about 20 cm) to describe the estimation and measurement.
