Primary 2 - Measurement and Geometry

Standard 2.MD.1 - Add and subtract metric units of length with word problems.

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.
