Solving Linear Systems by Graphing Coloring Page!
Inspired by the work of New Jersey teacher
(If you haven’t checked out this teacher’s work, you should!)
Lafayette High School student teacher, Megan Stanford, wrote this Halloween coloring page as an assignment for one of her undergraduate classes at the University of Mississippi, and we used it with our algebra students with great success.
There are 6 linear systems to solve by graphing. Have students show their work (solving for y, plotting points, etc.) and make the graphs, then write down the coordinates of the intersection. Once they are finished, or even as they go, they can check their answers on the second page. Have them write “1” next to Qs (for questions) if they think its solution is in that column. Then, they should color the blocks with a “1” that color.
The answers are there and if done correctly, the colorful drawing should be obvious! The teacher should work it ahead of the students to ensure the correct colors. I am not providing an answer key since students (and parents) could just download it for free and teachers would not appreciate that! Also, if the teacher works it ahead of time, s/he can decide if students should use a calculator or not and what kind.
If you are stuck or feel there is an error, email me at firstname.lastname@example.org.
Happy Coloring! (Actually, some of my high school students DID NOT want to color and I told them that was ok as long as their work graphing was correct.)
