Measuring with different units

Mathematics · Measurement · conceptual

Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen

Sign in to track this

What mastery looks like

  • Measure a desk in both centimetres and inches and compare the two numbers
  • Explain that measuring with a smaller unit gives a larger number
  • Predict whether a measurement in centimetres will be greater or less than in inches

Check your understanding

If Measuring with different units measures the same book in centimetres and then in inches, can they explain why the numbers are different even though the book hasn't changed size?
