Fri Feb 3rd – Converting between metric units

LEARNING OBJECTIVE: TO understand how the metric system works

SUCCESS CRITERIA: You will be able to convert between metric units – eg convert cm to m, mm to cm, g to Kg,

STARTER:

Write down all the different measurements we use to measure the length of something

Write down all the different measurements we use to weigh something (or someone?)

LESSON: Use answers to Starter to discuss Metric and Imperial Measurements

Look at the Metric Ladder of prefixes from mm to Kilo
