Instructional Ideas

  • Consult a science teacher for additional examples and contexts
  • Extend the lesson by challenging learners to attempt graphical and tabular methods to solving exponential equations
Classroom Considerations

  • Pupils should have previous experience solving exponential equations, such as 2^x = 16, where the solution is an integral value
  • The seventh installment of a 35-part module

  • Resource includes answers for all examples, problems, and guiding questions
  • Teacher guide thoroughly explains how the lesson connects and leads to future lessons, giving instructors a clearer view of the objectives

  • None
