4th Grade Everyday Math (V3) Unit 1 Geometry Vocabulary Flash Cards

This set includes 33 flash cards. For each term there is a short definition and a picture. For that reason, these are great to use with ESL students. I put them on a binder ring and have these students use them as we go through the practice pages.

The numbers in parentheses refer to the Everyday Mathematics lesson that it is aligned to, however, they can be used with any curriculum. They are common core aligned to

CCSS.Math.Content.3.G.A.1 Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

CCSS.Math.Content.4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

CCSS.Math.Content.4.G.A.2 Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
