ABSTRACT
This chapter describes a lesson where students learn about logarithms through problem solving. These problems include investigating how many times a piece of paper can be folded in half; how many folds it would take to reach the moon; and how the teacher is able to give the log of any number without using a calculator. The lesson started with the teacher giving the class a piece of A4 paper and asking them how many times they could fold it in half. The teacher asked the learners which factors would contribute to helping get to seven folds; the students are quick to suggest that the thickness and the size of the paper would both influence the answer. The lesson was very successful at engaging the students who came up with, and shared, important insights throughout.
