Equal sharing and grouping
Sharing equally means everyone gets the same. Deal the objects out one at a time: one for each friend, then go round again, until none are left. Then count what one friend has. To make groups, fill one group, then the next, and count the groups. A share is fair when every plate has the same number. If one plate has fewer, count on to see how many more it needs.
