Quadratic Sequences: Finding the Nth Term
Students will identify quadratic sequences and determine their nth term rule, involving second differences.
Key Questions
- Analyze the relationship between the second difference and the coefficient of n^2 in a quadratic sequence.
- Construct a systematic method for finding the nth term of a quadratic sequence.
- Differentiate between linear and quadratic sequences based on their differences.

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.
