K-5 Mathematics Foundational Training session is a pre requisite for this session. This 3-hour session is a dive into the Alabama 2019 Course of Study: Mathematics where participants will explore the conceptual framework of the ALCOS (four critical components: Position Statements, Student Math Practices, Math Teaching Practices, and the Alabama Content Standards). Participants will become familiar with the structure of the ALCOS, discover themes and learning progressions, and uncover connections and relationships between components that are critical for effective elementary mathematics instruction.
