This chapter for Algebra focuses on systems of equations and solving systems of equations. All of the content is embedded in a real-world, cross-curricular context. Included in the chapter are teacher resources and student notes, practice opportunities, and assessments for all three different ways to solve systems. The note sheets follow the widely accepted practice of "I do, We do, You do." The practice resources offer individual, partner, and group learning activities and components. The assessments are formative and summative. Additionally, there are clearly defined application pieces that correlate to the over-arching project.
