How about a mathematical twist to a old game? The game Doggie, Doggie has entertained countless students throughout the years. This activity involves the whole class in finding Doggie's bone-SmartBoard style. The SmartBoard has hidden points that will be revealed by touch. The students will connect the points to reveal that Doggie's bone has been in his doghouse the whole time.
Optional activity-Students can be involved at their desks and the SmartBoard. They will plot points on their sheets, while each student takes a turn at the SmartBoard. See my Doggie, Doggie, Where's Your Bone Coordinate Graph Activity. It has two additional activities involving independent work with coordinate graphs and ordered pairs.
