Factoring Special Cases
Students will identify and factor differences of squares and perfect square trinomials.
Key Questions
- Analyze the structure of a difference of squares and explain why it factors into conjugates.
- Predict the outcome of factoring a perfect square trinomial without explicitly multiplying.
- Critique the efficiency of using special product patterns versus general factoring methods.

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.
