- Definition
A metric unit is a standard way of measuring things like length (e.g., metres), weight (e.g., kilograms), or time (e.g., seconds) that is used in many countries around the world.
Measuring the length of a pencil in centimetres is an example of using a metric unit.
How to teach this in 30 seconds
Try this analogy: Metric units are like a special set of building blocks where you can trade 10 small ones for 1 medium one, and 10 medium ones for 1 big one.
Ask your child: What measurement words do you see on this milk carton or juice box?
Common mix-up: Kids may confuse metric units like centimetres with other units like inches. The metric system is a different 'family' of measurements that neatly builds on groups of ten.
Examples
- Checking the weight of an apple in grams at the grocery store.
- A milk carton holding 1 litre of milk.
- A short race at school being measured in metres.
metric unit is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
