This is a power point activity that can be used to strengthen student speed and accuracy of problems related to properties of logarithms.
On each slide, a problem will appear for a short amount of time, followed by the correct answer. The times are set in the power point ranging from 7-15 seconds per problem, depending on the difficulty level of the problem.
I use this with my honors level, and it is designed to not give them any extra time. I have students write down answers on their individual whiteboards and hold them up, but this could easily be done with pencil and paper.
This activity lasts about 20-30 minutes, depending on how often you need to stop to give explanations or go back to the problem.
