Introduction to Functions: Special Relations
Students will identify functions as special types of relations where each input has exactly one output.
Key Questions
- Compare and contrast a general relation with a function.
- Justify why a vertical line test is effective for identifying functions.
- Predict the output of a simple function given an input and its rule.

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.
