Manage your students while teaching them about Native American cultural groups. I divide my students into the 5 regions and at the end of the day one group gets an "icon" the group that has the most "icons" on Friday gets a reward. In the Pacific Northwest Native Americans had potlatches in which the host would give out wonderful gives, so I usually tell the group that they win the "potlatch gift" because they had the most "icons". The teacher gets to choose the reward! Make sure you save an original blank template and then save a template for this year's students. They will tell you if you don't save it and an icon is lost. The original will keep the grid clear for you for next year!
