Angles in Triangles and Quadrilaterals
Students will understand the sum of angles in triangles and quadrilaterals and use this to find unknown angles.
Key Questions
- Explain why the sum of angles in a triangle is always 180 degrees.
- Predict the measure of an unknown angle in a quadrilateral given three angles.
- Design a proof to show that the sum of angles in a quadrilateral is 360 degrees.

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.
