Students have learned a lot about linear equations over the past several weeks. They know how to graph linear equations, and also how to write the equation of a line based on its graph. Students have also been doing a lot of algebraic work to solve problems, like determining if a given point is on the graph of a linear equation or writing the equation of a line that goes through 2 points.
Now, students are reviewing all that they have learned about linear equations. One way students are reviewing is by playing games. In the game "Equations of Attack," students placed 'ships' (colored points) on a coordinate plane. The goal of the game was to shoot cannons in a straight line from the y-axis and hit their opponents' ships. To determine the slope of their line, students selected a card with a number on it. To determine whether they needed to shoot from an odd or even number on the y-axis, students flipped a coin. They then got to chose which cannon to shoot from, trying to create a line with their selected slope that would hit their opponents' ships. Students practiced using slope and y-intercept to create a line, and also had to determine if a given point would be on their line. Here's a link to the directions of the game (we modified them slightly to work for their groups of 3).
