Measurement > Direct Comparison

Australian Curriculum Version 9 Says:

Identify and compare attributes of objects and events, including length, capacity, mass and duration, using direct comparisons and communicating reasoning.

What this means

When comparing length an item might be longer or shorter than another item. Direct comparison example: placing two sticks next to each other to compare the lengths.

  • At this level, students are not using units of measurement.
  • Students also aren’t ordering yet (comparing 3 objects) – that is in Year 1.

Tips

  • Activity: Have students stand back-to-back using the language ‘shorter’ and ‘taller’.

Comparisons

  • Capacity Comparisons – e.g. “holds more” / “holds less”
  • Mass Comparisons – e.g. “is heavier” / “is lighter”
  • Duration Comparisons – e.g. “longer time” / “shorter time”
