Dependency Diagram

unit dependency chart

In the unit dependency chart, an arrow indicates that a particular unit is designed for students who already know the material in a previous unit. Reversing the order would have a negative effect on mathematical or pedagogical coherence. Some dependencies are needed to address the standards. For example, there is an arrow from G.3 to G.4, because students learn that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. Some are a consequence of choices made by the authors. For example, there is an arrow from A1.5 to A1.6, because when quadratic functions are introduced, they are contrasted with exponential functions, assuming that students are already familiar with exponential functions.

The following chart shows unit dependencies across the 6–12 curriculum.
