Tutorial

## Overview

Welcome to our solving equations with variables on both sides tutorial. This page includes access to resources and guided practice for 3 of the 4 stations that you will visit during this exploration. Videos may be assigned to complete in class with your small groups, or may be assigned to view in a flipped classroom scenario.

While working though each station, you will be completing a graphic organizer. Your options for a graphic organizer include:

• Printing off the template of a mind map below and use low-tech enhancements (markers, Post-Its, highlighters, etc) to make it meaningful.
• Downloading the template and typing into it. You may include images and videos. Consider taking pictures of your own work and integrating it. Enhance your mind map with color, highlighter, etc.
• Creating a mind map/presentation using PREZI

• Pertinent information about utilizing each model for solving equations
• 1-2 examples of how to use each model

## Independent Practice

Select one of the two games listed below to practice your selected method(s) for solving equations with variables on both sides.

• You must complete at least 10 problems with equations with variables on both sides.
• You may start with easier problems, but you must complete practice at the level of the standard.
• Record your work on a separate sheet of paper and submit it to your teacher.
