What is comparing length?
Before rulers, children compare lengths directly (lining objects up) and measure with informal units like blocks or paperclips laid end to end, then compare the counts.
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
Computed from a real worksheet, so it is correct.
Common mistake
Not starting both objects from the same line, and leaving gaps or overlaps between informal units so the count is off.
