In The Line Game students are woking in small groups to quickly and accurately match attributes of a line to a line that is displayed. Students are matching 2 points to a line, slope and y-intercept to a line, equation to a line, x- and y-intercept to a line, and slope and a point to a line. Inaccurate answer will result in points lost for a team, while accurate answers result in points gained. The quicker the team is to answer accurately, the more points they receive.
I have played this game with my students for many years and they love it. Even the most reluctant students can't resist a time pressured game.
