Classifying Three-Dimensional Shapes: Pyramids, Prisms, and More

In this instructional activity, students will engage in the classification of three-dimensional figures such as pyramids, cones, prisms, and cylinders using geometric vocabulary and properties. The activity is divided into four parts. Students will observe various structures, identify their characteristics like base shape, number of triangular faces, edges, and vertices, and classify them accordingly (e.g., triangular pyramid, rectangular pyramid, etc.). This practical exercise enhances spatial reasoning and geometric understanding.

  1. 7.6C Instructional Activity #2 (7.6) Geometry and spatial reasoning The student compares and classifies shapes and solids using geometric vocabulary and properties. The student is expected to: (C) Use properties to classify three-dimensional figures including pyramids, cones, prisms, and cylinders.

  2. Edge Face Vertex Base Pyramids • A pyramidis a three-dimensional figure with only one base. • The base can be any polygon. The other faces are triangles. • A pyramid is named according to the shape of its base. The base in the pyramid below is a square, so the figure is a square pyramid.

  3. Face Edge Vertex Base The base in the pyramid below is a rectangle, so the figure is a rectangular pyramid.

  4. 7.6C STUDENT ACTIVITY #2 • PART I: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a __________ __________.

  5. 7.6C STUDENT ACTIVITY #2 • PART I: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a __________ __________. triangle one three six four triangular pyramid

  6. 7.6C STUDENT ACTIVITY #2 • PART II: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a __________ __________.

  7. 7.6C STUDENT ACTIVITY #2 • PART II: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a _____________ __________. rectangle one four eight five rectangular pyramid

  8. 7.6C STUDENT ACTIVITY #2 • PART III: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a ___________ __________.

  9. 7.6C STUDENT ACTIVITY #2 • PART III: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a ___________ __________. pentagon one five 10 six pentagonal pyramid

  10. 7.6C STUDENT ACTIVITY #2 • PART IV: Look at the figure. • The figure shown has __________ base shaped like a __________. • The figure has __________ triangular faces. • The figure has __________ edges. • The figure has __________ vertices. • The figure is a __________ __________. 11 11
