Young elementary-schoolers are constantly reminded to share with others. Use this familiar concept in this equal distribution activity. Scholars choose either 10, 16, or 28 as the number of marbles they have to give out. Then, they determine how many friends they can share with, giving everyone equal amounts. They are encouraged to come up with  multiple solutions if possible, and illustrate their processing. Consider using actual marbles to help kinesthetic and visual learners.
