What does this exercise practice?
Sharing fairly prepares for halving and later for dividing and makes the half easy to picture.
Common pitfalls
With odd amounts the fair share does not come out evenly. Here only even amounts are chosen.
How to practice at home
Share eight cookies fairly onto two plates and check whether both plates are equally full.
