Things can be measured. We can ask: How long is it? How tall is it? How heavy is it?
- Long or short: how far it goes from end to end.
- Tall or short: how high it stands.
- Heavy or light: how hard it is to lift.
Key idea
Length, height and weight are things we can measure. Color and name are not.
Why it works
Measuring tells “how much.” A thing can have more or less length or weight, but it cannot have more or less “red.”
Worked example: A backpack
What can you measure about a backpack?
- Lift it: how heavy is it?
- Look from bottom to top: how tall is it?
- Both of these can be measured.
Answer: How heavy it is and how tall it is
For grown-ups: Use the words long, short, tall, heavy and light in everyday talk: “This bag is heavy. This ribbon is long.”
