This activity focuses solely on evaluating algebraic expressions by way of real-world application. Students will need to have knowledge of writing algebraic expressions from word problems in addition to evaluating these expressions given an input value. This activity also enlists the use of multiple representations because students will need to create a table and a graph that will coincide with their algebraic expressions. I've used this as an end of the unit project or as an in-class activity. This activity could also be great for introducing systems of equations by graphing.
I've assigned each question a point value to make grading this activity easier. You may use it if you'd like!!!
Also, here's a site where graph paper can be found if you don't have access to your own: https://www.mathworksheets4kids.com/grid/25by25-positive-noscale1.pdf
Hope you enjoy!!!
