The Center for Algebraic Thinking introduces Point Plotter, a game that tests your knowledge of the 2D coordinate system and your ability to recognize patterns.
The premise is simple: you are shown a line segment, and you must identify as many points as possible that lie within that line segment. But you have just two minutes per round to do that. Submit enough correct points and you will make your way to the top of the High Scores list.
After the time runs out, you have a chance to earn bonus points if you can correctly write in the equation for the line that all of the correct points lie on.
With three difficulty levels, you will be challenged no matter what your current skill level.
