### Equations and Inequalities Unit

This week we completed our geometry unit and started our final math unit of the year on algebra.  Students will practice four skills:

-Solve multistep equations.
-Solve equations that have variables on both sides.
-Read and write inequalities and graph them on a number line.
-Solve multistep inequalities.

Today your child received a practice packet with worked examples of all these skills.  We will focus on pages 556-601 in our textbook.  We will also use Gizmo, Khan, and other resources to practice these important skills.  The quiz is scheduled for Tuesday, May 17th and the final test Tuesday, May 24th.

You can find an online PDF copy of our packet here:  https://drive.google.com/file/d/0B0pphv4klPajRjdZM1ZTSEVaNms/view?usp=sharing

### Geometry Update

After using several weeks of class time to practice identifying polygons, calculating their areas, and plotting their vertices as ordered pair, we are now moving into three-dimensional geometry.  We will find the volume of solids and draw their nets on a coordinate plane to calculate their surface area.

This website has several interactive solids and nets:  https://illuminations.nctm.org/Activity.aspx?id=3521

I posted many geometry games on 3/14:  http://mrhartwell.blogspot.com/2016/03/geometry-games.html

### Chess and Go

You can learn chess through many websites.  Chesscademy is a site I like.  It's set up in a similar way to Khan Academy.

You can learn and play Go through this great website.  You can even challenge your friends remotely.
