2. 3-DIMENSIONAL FIGURES

3. WHAT ARE THEY? 3-Dimentional figures are shapes that have height, length, and depth

4. HOW ARE THEY DIFFERENT FROM THE SHAPES WE KNOW? 2-Dimensional3-Dimensional http://www.sciencebuddies.org/science-fair- projects/project_ideas/Math_p045.shtml#background http://www.mathwithlarry.com/lessons/lesson008.htm

5. 2-Dimensional Shapes3-Dimensional Figures Can Measure Height and Length Can Measure Height, Length, and Depth Has Just One ShapeCan Have Multiple Shapes Within the Figure Has Lines and VerticesHas Edges, Faces, and Vertices What Are the major differences?

6. FIRST, LET’S LEARN ABOUT A 3-DIMENSIONAL FIGURE! Notice how the Face is a 2-Dimensional shape Edges are what connects the 2- dimensional shapes Vertices are the corners http://www.narragansett.k12.ri.us/resources/necap%20support/gle_support/Math/resources_geometry/3d_shapes.htm

7. HOW IS A FIGURE PUT TOGETHER? http://www.learner.org/courses/mathilluminated/units/5/textbook/03.php

8. Let’s learn the different figures! Which figure do you want to learn about?

9. Prism Prisms are figures that have two parallel bases. This prism is a triangular prism because the bases are triangles

10. Cube A cube has 6 faces All faces are squares

11. Cylinder A cylinder has two circular bases that are congruent and parallel

12. Pyramid A pyramid has only one base The faces meet at a point called the apex. This pyramid is a square pyramid since the base is a square.

13. Sphere A sphere is like a ball Any point from the outside will be the same distance to the very center There are no edges, faces, or vertices

14. NOW LET’S TEST WHAT YOU LEARNED!

15. WHICH FIGURE IS A PYRAMID? AB
