Angles in Triangles and Quadrilaterals
Students will find unknown angles in triangles and quadrilaterals using angle properties.
Key Questions
- Explain why the interior angles of any triangle always sum to 180 degrees.
- Analyze how vertically opposite angles help us navigate complex geometric diagrams.
- Predict the measure of an unknown angle in a quadrilateral given other angles.

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.
