This web page is the second of the eight pages of the Inside Mathematics initiative to help guide and support educators in understanding the math practices and to see instances of teachers engaging students in abstract and quantitative reasoning by helping them to make sense of quantities and their relationships in problem situations. Included are various classroom connections: classroom observations and video examples in various grade levels of teachers engaging students. The video clips are excerpts from public lessons: "Proportions and Ratios" and Numeric Patterning" (each cataloged separately) and include links to a teacher commentary, transcript, and a related math task with examples of student work.
