Previously Published Data 

1.) Have students graph a function and its inverse. 

2.) After students are taught graphs, have them graph x = 10 to the y and y = logx. They should discover that it is the same graph and that x = 10 to the y and y = log x are equivalent. 
3.) Have students find the log of 10, 100, 1000 and come up with a general statement of log b to the x = x. 
4.) Have students simplify logs. 
5.) Have students solve various equations where they have to convert from logarithmic form to standard form. The base number stays as the base. The exponent becomes the answer. The response number becomes the log number. The x and y change places. 
Previously Published Data 

1.) Have students graph y = 3 to the x, x = 3 to the y, and log3y = x on the same graphs. 

2.) Have students report on real life applications of logs such as determining the strength of an acid by its pH or the magnitude of an earthquake. 
3.) Have students explain the relationships between exponents and logarithms in both word and (number) examples.
