Classifying Shapes

1. Classifying Shapes MA.3.G.1

2. 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.

3. 1 How many line segments does this shape have? Identifying Number of Line Segments

4. 2 How many line segments does this shape have? Identifying Number of Line Segments

5. 3 How many line segments does this shape have? Identifying Number of Line Segments

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

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

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

9. 1 A shape has six sides. If it is a polygon, how many angles does this shape have? Determining Number of Angles from Sides

10. 2 A shape has seven sides. If it is a polygon, how many angles does this shape have? Determining Number of Angles from Sides

11. 3 A shape has eight sides. If it is a polygon, how many angles does this shape have? Determining Number of Angles from Sides

12. Target practice Strategy # 1: Cubes Strategy CIRCLE the numbers UNDERLINE the key words BOX the question ELIMINATE the extra information and SOLVE the problem Strategy # 2: T-1-2-3-4 Strategy Strategy # 3: Draw a picture or an array Use dots, squares, circles, lines, boxes, or number lines. Strategy # 4: Create a Table
