Teaching guide
Measure the length of shapes and objects with informal units, learning that the units must be the same size and placed end to end.
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.
Generated and checked in code, so it is correct.
Not starting both objects from the same line, and leaving gaps or overlaps between informal units so the count is off.
