    I am struggling to write a geometry unit for gr. 3. There are only 2 standards and the first is broad. Children need to be able to understand that “shapes may share attributes, and that the shared attributes can define a larger category.”

    Is there a listing of attributes/vocabulary (with definitions) that third graders are expected to know? Do they need to know the terms vertex or angle, parallel, right angle, ray, line, etc.?

    Hi! Have you read the Geometry progression for K-6. I know your question is specific to 3rd grade but you might find your question answered by reading the entire document. It can be found here http://commoncoretools.files.wordpress.com/2012/06/ccss_progression_g_k6_2012_06_27.pdf

    Also, you might look in the K6 Geometry section of this forum. I often find I am not the first to have a question and, therefore, can find an answer there.

    Hope this helps!
