It is at the middle school level that geometry really gets exciting, as applications to the real world become more apparent. Beginning in 6th grade and going through grades seven and eight, middle school students progress from solving problems of volume and surface area to studying the relationships between geometrical figures and then to real-world problem solving using cylinders, cones, and spheres.

The math vocabulary lists are based on the Common Core Middle School Math Standards. VocabularySpellingCity has selected the middle school math words that apply to the key math concepts and written level-appropriate middle school math definitions combined with meaningful example sentences. Middle school students can use these materials for reinforcement to build understanding or assessment. Teachers can import the lists into their account and then edit or extend the lists for their own purposes.

Common Core State Standards Overview for Middle School - Geometry

6th View Our Lists	Solve real-world and mathematical problems involving area, surface area, and volume.
7th View Our Lists	Draw, construct and describe geometrical figures and describe the relationships between them. Solve real-life and mathematical problems involving angle measure, area, surface area, and volume.
8th View Our Lists	Understand congruence and similarity using physical models, transparencies, or geometry software. Understand and apply the Pythagorean Theorem. Solve real-world and mathematical problems involving volume of cylinders, cones and spheres.
