Welcome to Market Day! To see which is longer, put two things side by side, with the ends lined up. The carrot is longer than the banana.
The banana is shorter than the carrot. Shorter means it doesn't reach as far.
Watch out! These ends aren't lined up. The pencil looks like it goes farther, but that's not fair.
Your turn! Tap the pencil to slide it over, so the ends line up. Now which is longer?
With the ends lined up, we can see it: the crayon is longer than the pencil, and the pencil is shorter than the crayon.
Try it with a grown-up! Find two spoons or two shoes. Line up the ends. Which one is longer?
