Modeling ratio, rate, and proportion using multiple representations is the focus. Double number lines, tape diagrams, and the Cartesian coordinate plane are models for proportional reasoning. Computation with fractions will also be modeled on the Cartesian coordinate plane as it is an effective representation for visual learners or for remediation.
