An introduction to solving systems of equations using substitution and elimination. There are both applications based and non applications based problems.
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.

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

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

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 \(a\).

This lesson introduces completing the square as a means of expanding the set of quadratic equations that may be solved beyond the extraction of roots and factoring.

Treating slope as a rate of change of two quantities with different units. There are both applications based examples and non contextual examples.
This lesson begins with linear equations and inequalities in one variable and then moves on to linear equations in two variables.
This activity leads students to understand the utility in the factored form of a quadratic equation. Students then express quadratic equations in standard form in the corresponding factored form.

This activity begins by reviewing conversions between fractions and decimals with an emphasis on repeating decimals.
