This session is based on the learning progressions focusing on ratios and proportional reasoning from sixth to eighth grade. Participants will engage in developing a deeper understanding of this foundational content, how to build fluency from conceptual understanding within these standards, and how to make instructional decisions responsive to the needs of each student. The math content in this PD is aligned to the ACT Aspire, primarily the reporting categories of Ratios and Proportional Relationships, Modeling, and Justification and Explanation.
