Measure mass in whole kilograms and grams
Lesson details
Learning outcome
I can use whole kilograms and grams to measure the mass of objects.
Key learning points
- 1 kg is equivalent to 1000 g.
- The mass of heavy objects can be given in whole kilograms and grams.
- We can use our knowledge of 1 kg and the composition of 1000 to determine the mass of objects.
Keywords
Mass - Mass is a measure of how much matter something contains. It is measured by how much something weighs. Mass can be measured in kg and g.
Gram - A gram is a metric measure of mass. A paper clip has a mass of about 1 gram. The abbreviation is g.
Kilogram - Kilograms are use to measure the mass objects that are heavy. A pineapple has a mass of about 1 kilogram. The abbreviation is kg.
Common misconception
Composition of 1,000 is Year 4 content so children may make mistakes when giving masses in kg and g.
Use of stem sentences to help: 1,000 is composed of __ equal parts of __.
Teacher tip
This lesson should be completed practically where possible to give the children hands on experience of what kilograms feel like and of reading scales where an object is not an exact number of kilograms.
