Elementary school is an exciting time as students begin to learn geometry concepts and discover that this branch of mathematics encompasses much more than just shapes, lines, and angles. From kindergarten to third grade, elementary school students do spend time learning shapes and their attributes, but by the 4th grade, they begin to learn shape classification using lines and angles. Older elementary school students also come to understand how to use shapes on coordinate planes to solve real-world problems.

The math vocabulary lists are based on the Common Core Elementary Math Standards. VocabularySpellingCity has selected the elementary math words that apply to the key math concepts and written level-appropriate elementary math definitions combined with meaningful example sentences. Elementary 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.

Return to Math Vocabulary Overview.

To learn these geometry concepts, all students must fully understand geometry terminology. This is why VocabularySpellingCity provides fun and entertaining word games based on geometry word lists, along with printable worksheets and even online progress assessments. The elementary geometry word lists conform with Common Core State Standards. As elementary school students have fun learning geometry vocabulary, the understanding they gain paves the way to a fuller grasp of the geometry concepts themselves, ensuring their knowledge of geometry is in great shape!
