What Are Logarithms?

What Are Logarithms?

A logarithm determines how many times a certain number must be multiplied by itself to reach another number.

"Worksheet with list of functions that precalculus students ought to come to know very very well (y=x, y=x^2, y=x^3, y=x^-1, y=x^1/2, etc). Early in the year, I spend five minutes of class having students fill out as much of the first page as they can and then I collect them (but don't grade them). We repeat this off and on until most people can do the whole page in five minutes. Later, we do the same thing with the second page (trig, log and exponential functions).

Laws of Exponents Foldable

This is a foldable I created for my Algebra students when they were learning about exponent rules. (I added combining like terms at the bottom too). Print front to back, fold in half and cut across the dotted lines!

What a great use for buttons! Gorgeous Button Art!
