This lesson tackles a famous fast food internet problem in a way that develops the concepts students need to make sense of Algebra. It is done in a way that no formal Algebra is used, but instead is heavily reliant on language and logical approaches to make sense of a confusing problem.
The lesson takes about a single class period, and there are notes in the PowerPoint to guide you with both pacing and discussion. To view a video I made using this powerpoint, click here: https://youtu.be/miVVsId_jjk
There is a teacher's notes slide in the PowerPoint that helps frame the objective of the lesson and the methods used to help promote student learning.
The powerpoint has very little, if any written text, it is highly visual, so it is highly engaging to students.
