More information

Use string cut to each child's height as a physical comparison tool — powerful and tactile.

Mark heights with chalk or a stick in soil if no wall is available.

Do children align objects at the base when comparing? Can they order more than two heights?

Use string, a strip of bark, or a length of vine cut to match a child's height. Mark heights with a notch in a stick or a line in soil.

Children often compare heights without aligning the base, leading to incorrect conclusions. Always ensure both objects or people are standing on the same level before comparing.
