Different units of measurement are used for familiar everyday objects found in the home. The objects are: a bag of potatoes, milk, kitchen foil, butter, orange juice and shampoo. The measurements of grams, kilograms, litres, millilitres and metres are used to match up the objects.
Look at the items shown in the clip. Can the children order them from heaviest to lightest? (Ideally the same objects will be in the classroom). Can they be arranged longest to shortest? Get the children to discuss how else they might be sorted. Introduce or familiarise the children with the term 'grams' and 'kg'. Using the scales, get the children to weigh a set object guessing whether they are less than 1kg, = 1kg, > 1kg. They can then group the objects accordingly.
