Mass can be measured in grams and kilograms
Lesson details
Learning outcome
I can describe the mass of a kilogram and a gram, and choose which unit might be best to measure different masses.
Key learning points
- Mass is measured in grams and kilograms.
- 1 kg is about the mass of a laptop or a bunch of bananas.
- 1 g is about the mass of a raisin or a paper clip.
- You can use scales to measure mass.
Keywords
Mass - When you measure how heavy something is, you are measuring its mass.
Grams - A measure of mass (about as heavy as a raisin).
Kilograms - A measure of mass (about as heavy as a laptop).
Common misconception
Children may not read scales accurately, particularly when the type of scale changes from a horizontal line to a circular scale.
Allow plenty of opportunities to explore different types of scales. Find where the same mass would be on different scales and talk about what is the same and what is different about each scale.
Teacher tip
When planning for practical opportunities, consider the numbers involved on the scales you choose to use. Pupils will be most secure working within 100. For pupils who have a good understanding of reading scales, you may wish to introduce examples that are between two marked intervals.
