The Domino Effect

Mathalicious posted on Twitter a lesson involving real world math. He created a math lesson based on figuring out how much Domino's pizza charges for pizza. His objectives were for students to understand the ideas of slop and y-intercept within the context of Domino's pizza pricing, to write and graph a linear equation given two points on the line, and to understand what it means for a function to be linear (constant rate of change). The students were to use linear equations to find the base price (y-intercept) and cost per additional topping (slope).

Mathalicious takes the students to the actual Domino's website through a tutorial. He completes an order and then has the students compare the items from his order to answer the question. I think this is an excellent real world lesson. Kids love pizza and almost every kid has ordered pizza once in there life. So it becomes something that all the students can relate to, which in turn makes the lesson more interesting for them. It also draws their attention to look for little things like hidden fees and, depending on what you order, how to get the most for your money.
