Start the first cube at one end of the object. Put cubes end to end with no gaps and no overlaps until you reach the other end, then count them.
lengthhow long something is
unitthe same-size thing you measure with
end to endeach one touching the last, no gaps
measurefind how long something is
Watch for: Starting away from the end of the object. Leaving gaps or overlaps between cubes. Counting a cube twice, or counting past the end of the object.
At home: Measure a spoon, a book and a shoe with paper clips laid end to end. Which took the most clips?
