Graphing Systems of Equations Poster
(Power Washer Prices)
I just taught solving systems of equations by graphing in my Algebra 1 class and felt that the students would do well with a poster project to practice solving systems of equations by graphing and extend their reasoning skills.
I made a word problem to test their ability to write linear equations from a word problem, graph two lines on a blank x-y axis (1st quadrant only which is provided in download), and then analyze the graph and help the person in the scenario make their decision on the most affordable plan presented to them.
My students seem to really enjoy demonstrating their understanding through posters, getting to create an end product and incorporate their own sense of creativity with the set up, colors etc.
An added bonus: as a teacher in a school that requires the posting of student work to display high levels of understanding and application, this is an easy way to take care of that requirement with some nice looking posters from the students.
