Teaching guide

What students learn

Measure and compare length, capacity and mass using uniform informal units, choosing smaller units when more accuracy is needed.

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 spoon is 6 paperclips long. The crayon is 2 paperclips long. Which is longer?
Answer: spoon

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.
