What students learn

Directly compare and describe objects and events by attributes such as length, capacity, mass and duration, and explain their thinking.

How to teach it

Compare objects directly (line them up at one end) and by measuring with informal units, blocks or paperclips placed end to end with no gaps, then compare the counts.

Worked example

The shoe is 4 blocks long. The straw is 2 blocks long. Which is longer?

Answer: shoe

Generated and checked in code, so it is correct.

Watch out for

Not starting both objects from the same line, and leaving gaps or overlaps between informal units so the count is off.
