LOGARITHMIC EQUATIONS - Partner Activity "Make Compound Words"

This activity practices solving logarithmic equations (24 problems) using the properties of logarithms:

• Zero- Exponent Rule
• Product Rule
• Quotient Rule
• Power Rule
• One - To - One Property

Some of the equations need to be transformed from the logarithmic to exponential form. All of the equations result in quadratics. Extraneous solutions are NOT included, however students must check answers or determine the domain of the respective logarithmic functions. Common logarithms are included.

The amusing part of this product is creating compound words corresponding to each solution set of the quadratic equations given.

Activity Directions: Partners start solving their own set of twelve equations. (They have similar type of problems so to meet similar difficulties). Once students has found the solution set of each equation, they are given two tables to use. There is a word corresponding to each number written in table 1 . Using this table, students find which two words correspond to each solution set of their equations and make compound words. They record the solution set of each quadratic equation and write down the compound word corresponding to it in table 2 .

Students show down detailed solutions on student recording sheets specially designed for this activity.
