Constructing Quadrilaterals: Given Four Sides and One Diagonal
Students will construct quadrilaterals when four sides and one diagonal are given.
Key Questions
- Explain why four sides alone are insufficient to construct a unique quadrilateral.
- Construct a quadrilateral using a compass and ruler with the given measurements.
- Evaluate the importance of the diagonal in fixing the shape of the quadrilateral.

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.
