Game Over Gopher

Hungry space gophers are after the prized carrot. Defend the carrot by placing units on a coordinate grid. Game Over Gopher is Common Core-compliant and addresses topics such as plotting coordinate pairs, differentiating negative coordinates from positive coordinates, and identifying the four quadrants.

A finalist in the 2012 Serious Games Showcase & Challenge and gold winner in the 2013 International Serious Play Awards.

Game Over Gopher Overview
Game Over Gopher screenshot of instructions To establish a source of rubies (the game currency) players must correctly place ruby drills on the grid at the coordinates indicated.
Game Over Gopher screenshot of instructions The Carrot Launcher is one of the first tools players can buy to feed the invading gophers. (Feeding gophers keeps them from eating the prize carrot.) As the player drags a Carrot Launcher around the board to a strategic position, its x, y coordinates – for example (1, 7) or (4, 3) – are shown dynamically on the screen.
Game Over Gopher screenshot of instructions The Corn Silo is an advanced gopher-feeding tool players can access at higher levels. By toggling x, y coordinates, they aim the Corn Silo at a specific point in the gophers’ path. Corn is launched and fed to gophers as they reach that location.
Game Over Gopher screenshot of instructions The bonus round in Game Over Gopher reinforces players’ grid navigation skills in a new setting. In search of buried treasure (“the data”), players control the robot’s path by toggling x and y coordinates. There’s a bit of guesswork involved, which gives learners freedom to investigate directionality on the grid without feeling there are always “right” or “wrong “answers.

Game Over Gopher Common Core Standards
Standard Standard Description
6.G.3 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.
6.NS.6b 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.
6.NS.6c 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.
6.NS.8 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.
Math Snacks Game Guidelines

Here are some simple strategies for using Math Snacks games in your classroom.

  1. We know you may not have time to play the game all the way through. Play through at least the first level, and watch the Gameplay video for each one, to get an understanding of what changes from level to level.
  2. Watch the Teaching video for each game. Each is shorter than 10 minutes, and gives really important strategies for teaching with the game, and engaging students in follow up activities to help them apply what they’ve learned.
  3. Secure lab time and secure the proper number of computers or iPads for students. All games and animations are available online. Ratio Rumble, and Pearl Diver are also on the iPad. Most games will take 2-3 hours for students to play.
  4. Games can be played in different ways: students can play individually, in pairs, in small groups or in one large group using a Smartboard, depending on the technology available in your classroom or computer lab.
  5. Don’t be afraid to let the game teach. Math Snacks games aren’t designed to measure what your students already know, but to give students the chance go understand concepts. They won’t succeed at every level their first time playing, and they aren’t supposed to. Let your students make mistakes, talk with each other, create strategies and learn from those mistakes.
  6. Refer to the Teaching With guide for each game for more recommendations.
