2025 MidSchoolMath National Conference

Learn alongside a group of 7th grade students as they work on integer addition! In this session, you'll look at the 5 Phase Teaching Model from But Why Does It Work? by Susan Jo Russell et al from both the seat of the learner and as an analyst of instructional decision-making.

This interactive session will include opportunities for you to explore the mathematics of integer addition, analyze student-created representations, discuss how to use the student work as a basis for instructional decisions and examine the student-articulated general claims. You'll have the opportunity to practice making instructional decisions at a key moments in a students' journey and be able to consider implications for their own instruction.
