Systems of Equations: Making and Justifying Choices (teacher support)
Systems of equations appear frequently on the HSE exam, as well as almost all college-entrance exams. Our students really struggle with this material, especially since it is so often introduced without any real-world context or discussion of its usefulness. However, developing an understanding of how systems of equations work can pay big dividends both in and out of the classroom. The problems in this unit use real-world scenarios to present a scaffolded introduction to the topic. Students will continue to explore the many different views of functions, and they will learn how systems of equations can be a useful tool for drawing conclusions and justifying choices.
