Lesson Summary

You will learn to convert between metric speed measures.

Key Notes

  • Sometimes speed is measured in different units.
  • The units for speed can be converted to alternative units.
  • When converting, it can be helpful to think about a context.

Vocabulary To Learn

  • Speed: Speed is the rate at which something is moving. It is measured as the distance travelled per unit of time.

Speed is the rate at which something is moving. It is measured as the distance travelled per unit of time. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.
