LO: To use informal units to measure length.

  • Describe an object using the language of length, such as long / short / wide

  • Estimate and compare straight or curved objects to decide which is longer/shorter

  • Order sets of objects by their length

  • Find objects bigger/smaller/equal to a given object or unit of measure

  • Compare the length of objects by lining up the base

  • Count units and call it ‘measuring’ with limited accuracy

  • Estimate, measure and compare lengths using informal units

  • Recognise the need to avoid gaps or overlaps when measuring

  • Use ‘between’ to describe measurements; for example, the book’s width is between 7 and 8 hand spans

  • Understand that the use of different attributes can lead to different results when ordering; for example, this jug is taller than that vase, but it holds less

  • Choose and use the appropriate attributes and units of measure when responding to measurement situations

  • Recognise that unit length affects number of units
