Reflection: Developing a Conceptual Understanding Evaluating exponential and logarithms - Section 2: Evaluating logarithms

 

I have recently added an activity from NCTM Illuminations to help students understand the properties of logarithms.  This activity is called Logarithms Demystified. The students make simple slide rules and see how computations can be done with this simple calculator.  

After doing this activity we will prove the logarithm properties.
