The lesson begins with an exploration of the family of graphs of $$y = ax^2$$, with an emphasis on tracking the changes in the $$y$$-values for differing values of the parameter $$a$$.

The lesson begins with a situation where the height of a pop fly in baseball is modeled using a quadratic equation.

This lesson introduces quadratic equations and graphs. Equations of the form $$ax^2 + c = 0$$ are solved via extraction of roots.

An introduction to solving a 3x3 linear system of equations. Back substitution and triangular form are first introduced, and then a general procedure for solving systems is presented.
An introduction to solving systems of equations using substitution and elimination. There are both applications based and non applications based problems.
A calculator based introduction to systems of linear equations.
Using real world data, this lesson introduces linear regression using lines of best fit that may calculated by hand by selecting two pints that appear to fall on the line of best fit.
This activity or homework assignment requires students to use a computer to access data on population, earthquakes, and sound.
Students are asked to write inequalities based on given information and graph the two inequalities.
"Get the Lead Out" extends the study of exponential functions and can be used to introduce the use of logarithms to "un-do" exponential expressions in solving equations.
