Goal: Make a paper strip as tall as you are, and put all the strips in order by length
Predict and cut
Cut a strip of adding machine tape the height of each person.
Children decorate their strips.
Put the strips in order
Children arrange the strips along the wall or floor from shortest to longest.
If needed, show how to line up the strips at the bottom, so that the top of the strip shows height.
How much do we grow? (same as main activity.) After doing the activity, ask children to make a prediction: “If we do this in 3 months, will we be in the same order?” Save the strips or measure them and record heights. Then try it again in 3 months.
Heights at home (same as main activity). Send home adding machine tape so children can make strips for each family member.
Half the size (harder). Make strips for some adults. Ask children to investigate: “Is anyone half the size of an adult? How could we find out?"
