Exploring Quadratic Graphs from Tables
Students will generate tables of values for simple quadratic functions (e.g., y=x^2, y=-x^2) and plot points to observe the parabolic shape, without formal graphing of y=ax^2.
Key Questions
- How does the pattern of y-values in a quadratic table differ from a linear table?
- What is the effect of a negative coefficient on the x^2 term when plotting points?
- Predict the general shape of a quadratic graph based on its table of values.

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.
