# Math Topics K 5 Understanding Shape Plane Figures

Grade 3 (3.G.A.1) Reason with shapes and their attributes.
Ages 8 - 9

## Carroll Diagram (2D)

SUPPORTS 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.

Grade 4 (4.G.A.2) Draw and identify lines and angles, and classify shapes by properties of their lines and angles.
Ages 8 - 9

SUPPORTS 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.

## Symmetry Dragon

SUPPORTS 4.G.A.3: Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

## Present Perimeter

MEETS 4.MD.A.3: Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
