The bamboo that changed size
Ayu and Mei want to know how long a bamboo stick is. Ayu measures it with her hand and gets 6 hands. Mei gets 5 hands. They argue, because their hands are not the same size. The bamboo cannot be both 5 and 6. How can they get the same number? By the end I can measure and draw lengths with a ruler in centimetres and metres, and choose the right unit.
