Framework at a Glance Grade six marks a foundational year for building the bridge between concrete concepts of arithmetic and the abstract thinking of algebra. Visual representations and concrete models (such as algebra tiles, counters, and cubes) can help students develop understanding as they move toward using abstract symbolic representations. - Privately Read Middle Grades at a Glance Handout. - What do you notice about the progression of ideas?
