Evaluating and Interpreting Functions
Students use function notation to evaluate functions for specific inputs. They interpret key features of graphs, such as intercepts and intervals of increase or decrease.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.

Introduction to Functions
Students define functions as rules that assign exactly one output to each input. They identify functions from tables, graphs, and mappings.

Linear vs. Nonlinear Functions
Students compare properties of linear and nonlinear functions. They analyze rates of change to distinguish between straight lines and curves.
