Lesson 11: Intercepts, Solutions, and Factors

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

Quadratics, Development Math
Lesson 10: Extraction of Roots

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

Quadratics, Development Math
Lesson 9: Gaussian Reduction
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.
Systems of Equations
Lesson 8: Algebraic Solution of Systems
An introduction to solving systems of equations using substitution and elimination. There are both applications based and non applications based problems.
Systems of Equations
Lesson 7: Linear Systems
A calculator based introduction to systems of linear equations.
Systems of Equations
Lesson 6: Linear Regression
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.
Modeling: Dev Math, Linear Equations, Functions
Introduction to Functions - Basics and Applications
"Description: The main purpose of this lab is to understand work rates and how working together affects the time it takes to complete a large task.
Rational Functions, Exponentials, Equations
Car Loans - Real World Exponential Equation
This activity has been modified from Real World Learning Objects, Internet-based Activities for Higher Education. The need to access an online calculator has been removed.
