Welcome to the Common Core Geometry Wiki for sixth grade

Parallelograms, trapezoids, and more.

Hmm...What's the area of the shaded areas?

Use a geoboard to find the area.

If you are a student, parent, or teacher visiting this site, you will find numerous GeoGebra applets and instructional videos to reinforce core geometry concepts.
Both videos and manipulatives provide the conceptual understanding that lay the foundation to accomplish more challenging math tasks.

In addition levels of mastery are described and example tasks for each level are provided. A preliminary scoring rubric is also included.

Wikis for other 6th grade Common Core units of study are under construction. As they near "ready for publication" the links below will be activated.

Grade 6 Ratios and Proportions(still under construction, but activated)
Grade 6 Number System
Grade 6 Expressions and Equations
Grade 6 Statistics and Probability
