This product is designed to be used for groups of 2, 3 and/or 4 members!
It practices solving exponential equations with different bases using the properties of exponents and square roots without using logarithms. All the equations are of type “EXPONENTIAL FUNCTION = REAL NUMBER” and result in linear. There are included many examples where the base of the exponential function is a decimal, a fraction or an irrational number/square root.
Activity Directions: Partners will each have their own set of 10 exponential equations. They start solving and write down the solutions of the problems on the recording sheet provided or on a separate sheet of paper. Then students look for the numbers they have found on the “keyholes board” - a set of keyholes given with numbers on them. They find some of their answers written on the keyholes, so they get the correct keys to “unlock” them. Partners mark the “unlocked keyholes” on the board. They record which are the “unlocked keyholes” and count them. Partners show the teacher their results. The group which is ready first and who has worked correctly wins.
☝ SUITED TO DISTANCE LEARNING! You can teach your students over videoconferencing using the pages of this material, combining it with the screen sharing. You can use the problems in this document for homework assignment as well.
All answer keys are included.
Here is the link of my version LEVEL 1 of this product. It contains easier exponential equations where the base of the exponential function is a counting number.
