Comments:

This app provides practice with thinking about slope in a context, and pushes students to understand how manipulation of the slope and y-intercept influence the graph of a line.

Common Core State Standards:

Description:

Develop students’ understanding of points on a line, slope, and y-intercept with this game environment. Similar to the game “Battleship”, students graph submarine paths (lines) for a competing student to find. Dropping depth charges (x,y points), students seek the submarine. After a couple of hits, students use the points to identify the equation of a line to determine if they have found one of the submarine paths.
