Slope and Rate of Change
Students will calculate the slope of a line from a graph, two points, and a table of values, interpreting it as a rate of change.
Key Questions
- Interpret the meaning of a positive, negative, zero, and undefined slope in real-world contexts.
- Compare different methods for calculating the slope of a line.
- Justify why the slope represents the constant rate of change in a linear relationship.

Planning templates for Mathematics
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.
