Properties of Triangles (Classification)
Classifying triangles by their sides (equilateral, isosceles, scalene) and angles (acute, obtuse, right).
Key Questions
- Differentiate between the characteristics of equilateral, isosceles, and scalene triangles.
- Justify why it is impossible to create a triangle with two obtuse angles.
- Construct a triangle that fits a specific classification based on both its sides and 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.
