Explain that items can be compared using weight and mass
Lesson details
Learning outcome
I can compare items according to their mass.
Key learning points
- Know the language used when comparing mass, the ___ is heavier / lighter than the ___.
- Know when comparing items that are equal to each other in mass, we use the language of 'the same' or 'is equal to'.
Keywords
Heavier than - an object has more weight than another
Lighter than - an object has less weight than another
The same - exactly the same amount or value
Equal to - exactly the same amount or value
Common misconception
May find it hard to feel whether an object is heavier, lighter or equal to the mass of another.
Model using yourself as a scale in different ways - using both hands, picking one object up after another, then having one in each hand.
Teacher tip
In this lesson, we compare objects children may have never seen before. Try to share real-life pictures / videos of the objects to help children visualise their size.
