Solving Exponential Equations
Students solve exponential equations using logarithms, including those with different bases.
Key Questions
- Explain how the change of base formula allows us to solve exponential equations with different bases.
- Compare the methods for solving exponential equations when bases can be made equal versus when they cannot.
- Justify the steps involved in isolating the variable in an exponential equation.

Planning templates for Mathematics
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.
