Classifying Shapes MA.3.G.1

UNWRAPPED BENCHMARK MA.3.G.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. Determining Number of Angles from Sides Identifying Number of Line Segments Identifying Number of Angles

Identifying Number of Line Segments 1 How many line segments does this shape have?

Identifying Number of Line Segments 2 How many line segments does this shape have?

Identifying Number of Line Segments 3 How many line segments does this shape have?

Identifying Number of Angles 1 How many right angles does this shape appear to have?

Identifying Number of Angles 2 How many right angles does this shape appear to have?

Identifying Number of Angles 3 How many right angles does this shape appear to have?

Determining Number of Angles from Sides 1 A shape has six sides. If it is a polygon, how many angles does this shape have?

Determining Number of Angles from Sides 2 A shape has seven sides. If it is a polygon, how many angles does this shape have?

Determining Number of Angles from Sides 3 A shape has eight sides. If it is a polygon, how many angles does this shape have?
