Game Over Gopher helps kids have fun as they learn to identify and graph points on a coordinate plane. They'll place rubies (the game's currency) at given coordinates, use the coordinate plane to launch carrots and corn at gophers, and use x- and y-coordinates to direct robots to find buried treasure. Additional resources include a teacher guide, a teaching video, a list of Common Core coverage, and general guidelines for using Math Snacks in the classroom.
It's okay to turn your students loose with the game before you've covered these concepts more formally in class. The game isn't meant to assess; it's best at encouraging kids to explore concepts and learn as they play. Show your students the Teaching Video, and then have them play the game, either alone or with a partner. Afterward, come together as a class to discuss the experience and what everyone learned in the process. At the end of the unit, give your students a chance to play again for reinforcement. Have them reflect about how the latter experience was different from their first gameplay session.Continue reading Show less
Key Standards Supported
Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate. Apply these techniques in the context of solving real-world and mathematical problems.
The Number System
Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.
Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.
