Measure classroom objects in centimetres.
Cut strips to the nearest whole centimetre and create a spiral.
Measure capacities in litres
Investigate the numbers of mugs that can be poured from a teapot of given capacity. Make paper containers, then compare and estimate their capacities.
Sort a variety of containers under headings: more than 1 litre and less than 1 litre.
Interpret capacity data from a bar graph.
Estimate and order container capacity relative to 1/2 a litre and 1 litre.
Measure weights in g and kg
Record weights by counting the 100g weights in the balance scales and recording weights in grams.
Sort objects into categories by weight: less than and more than given weights.
Read the dials of weighing scales to the nearest 100g.
