This resource introduces the metric system and its basic units.

It includes a short historical overview to give context to how the metric system developed, along with simple explanations of how units are defined and used. Students are guided through key ideas such as standardisation of measurement and how units apply to length, area, and volume (e.g. square and cubic units).

The presentation is structured to support understanding of how and why the metric system works, rather than just memorising units.

What is included:

37-slide PowerPoint presentation
A student activity included at the end of the slides

Also included:

A short audio summary that reviews the key ideas from the unit. This can be used for revision or reinforcement.

This resource can be used as an introduction to the metric system or as a lead-in to a larger unit on measurement.
