Reflection: Real World Applications Elephant Tracks! - Section 2: Class Discussion


The attached student work shows two successful attempts at finding the age of an elephant.  These two groups not only utilized sound mathematical reasoning to complete the task, but they were also able to repeat their processes back to me when I asked.  It can't be seen from the pictures, but it was very helpful for the groups to solve the problem on the back of the footprint (or on a scrap piece of paper) before copying it on to the front with marker.  Other groups who calculated incorrect ages (they could tell when they were wrong) were frustrated by not first doing their work in pencil.

Elephant Tracks!

Unit 2: Exponential and Logarithmic Functions
Lesson 18 of 21

Objective: Students will be able to solve multi-step equations requiring logarithms to find the age of their elephant! Additional scaffolding and support are provided after the discovery.

Big Idea: This lesson teaches the students to use the natural logarithm function to find the age of an elephant!
