Celebrate Pi Day with this linear equation graphing activity. Students are given a list of linear equations each with a corresponding domain or range. The equations will occur in either standard form or slope-intercept form. When the students graph all of the equations, they will have a picture of the symbol "Pi." Don't forget to download a copy of my custom-made FREE GRAPH PAPER. Here are some tips: [1] A completed picture has been provided to be used as a key. [2] Use a ruler to align each line with its equation. [3] You can download my custom made FREE GRAPH PAPER from my store. [4] I have found that printing graph paper directly from themathworksheetsite.com helps out, but any graph paper will do. [5] Remember to copy double-sided to save paper. [6] Technology Option: Use your favorite equation and domain graphing software or website.
