Students enjoy online interactive assessment activities at Shodor Online. Activities such as "Whole Number Cruncher" that generates multiplication and addition functions to avoid outputting negative numbers, offer linear equation-related activity reasoning. Linear functions are also related in the "Number Cruncher" activity. Lists input and output on a table and users guess the rule with two data points. "Function Machine," found at the same site, allows students to investigate simple functions by trying to guess the algebraic form for the inputs and outputs, according to Shodor Online. Also one of the interactive assessment explorers, this activity is designed for middle or high school students.
"True Grid -- Equations of Lines" is a free online interactive gum-slinging game found at Fact Monster. Elementary students can help Cassidy move up the ladder to reach evil Gus by trying to hit the target line with gumballs. The equation above the grid defines the line. To graph the equation, use the slope and the "y" intercept by choosing the color that defines the "y" coordinate. Click on a gumball color to load the sling with gum for the "y" coordinate. For the "x" coordinate number, click a number from the top, left-hand panel. Click "Sling" to launch the gumball. This game, designed for elementary and middle school students, is an entertaining way to teach linear equation concepts.
This free online interactive game reviews adjacent supplementary angles, helping students review finding value concepts and graphing concepts related to linear equations. "Baseball Geometry -- Intersecting Lines" can be enjoyed with no download at Fact Monster Online. Students must answer graphing questions correctly within the game in order to go forward and stand ready to bat. The pitcher will pitch the baseball and the player must hit the ball at the correct angle in order to hit a home run. Intersecting lines, such as the ones provided within "Baseball Geometry," produce information for graphing basic linear equation systems.
Math.com offers an educational interactive graph to help students learn to use the slope and y-intercept. Graphing linear equations within the classroom becomes more entertaining when students use interactive online technology to help them achieve their goals by checking their answers or by helping them if they get stuck. This activity clearly defines three steps, from locating the y-intercept, to plotting the point, to using the slope to find a second point and plotting it. Finally, students can draw the line that connects the two points.
