Lesson details
Key learning points
- The mass of objects can be measured in grams.
- Different scales can be marked with different intervals.
- The mass of objects can be compared using scales.
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 grams.
Gram - A gram is a metric measure of mass (which we feel as weight). A paper clip weighs about 1 gram. The abbreviation is g.
Interval - Intervals are the spaces between given numbers. They include all given numbers between the numbers marked at the start and end.
Common misconception
When comparing masses - if the scales have different intervals or the zero is in different places.
Remind children that the scale is a number line and we always read number lines from zero; the further the arrow travels, the greater mass.
