# Stem Integrated Modules

## Overview

There are three weeks of online, stem-integrated modules. The first week is on Linear Equations, the second is Systems of Equations, and the third is Quadratic Equations. There is a teacher document that explains standards, links, and the order that everything is supposed to be viewed in. There is also a student checklist with links that provides the order in which students should be viewing the material.
