Disgusting? Yes! Engaging? Uh-huh! Appropriate level of difficulty? Yup! Great for practice? Absolutely!
This has been my go to activity for some years after discussing equations of lines. The game features cockroaches (I said it was disgusting...) running across a coordinate plane. Students determine the correct equation of the line formed by bugs running in a set path.
Level 1 starts off easy, featuring only vertical and horizontal lines, but the seven levels that follow get progressively more difficult.
Students work in pairs to reach a goal of Level 7.Invariably, those who struggle initially master the concept by the game's end.
