I always like to find activities (including games) which apply what you learn to a real situation – even Cathedral Architecture.
I just ran into a simple “Green Blobs” Equation Plotter Game in which students try to generate an equation which will hit the most green dots on the grid. I’ve seen math games “shooting” games before, but this Green Blogs is unique in that it uses a skill that does occur in real math.
For instance, statistical regression is basically trying find an equation that best “hits” the dots from your data set. It would be interesting to see if these kids made a connection later, but at least the idea won’t be a foreign concept.
