Description: This workshop will engage participants in hands-on activities focused on developing algebraic reasoning. Throughout the workshop participants will engage in content-focused sessions as well as sessions that highlight the mathematics teaching practices. The content for grade 6 will focus on concepts related to ratio, rate, and variable as fundamental concepts in the development of an understanding of expressions and equations. Grade 7 will focus on expressions and equations as fundamental concepts in the development of an understanding of functions. Grade 8 will focus on concepts related to functions that lead to an understanding of relationships among quantities represented in multiple ways. Additional content will highlight productive teaching practices that promote mathematical thinking in the classroom. These practices link to Principles to Actions and the Standards for Mathematical Practice. This content will address – facilitating effective mathematical discourse, building student responsibility within the community, and posing purposeful questions.
