Solving Systems by Substitution
Students will solve systems of linear equations by substituting one equation into the other.
Key Questions
- Explain when the substitution method is the most efficient strategy for solving a system.
- Analyze how isolating a variable in one equation facilitates solving the system.
- Predict the algebraic outcome when a system has no solution or infinitely many solutions using substitution.

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.
