Lesson Details
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.
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.
