Lesson Plan : Views of Three-dimensional Figures
Teacher Name: | Dorothea Mixon |
Grade: | Grade 7-8 |
Subject: | Math |
Topic: | Three Dimensional Views: Building, drawing,and analyzing a three dimensional figure. |
Content: | The student will become familiar with and use the terms views, isometric drawing, layers, and perspective to describe, draw and build a three dimensional figure. |
Goals: | After completing this lesson, the student will be able to describe, draw and build three dimensional figures from different views (side, top, back, bottom and front). In addition, the student will identify the number of layers the figure contains. |
Objectives: | The student will determine the correct view of a figure based on its orientation |
Materials: | Snap cubes, isometric dot paper, HD media |
Introduction: | Introduce students to the lesson by talking about different types of drawings that show perspective views. Ask students to describe what makes the artwork interesting. Discuss other professions that use drawings from different perspectives. |
Development: | Provide the opportunity for students to see a model of a three-dimensional figure (HD media). Explain the vocabulary in terms of the model. Ask students to count the number of squares with you as you identify the top view; side view; front view; back view. Explain why some squares facing the same way are not counted (they are blocked by a cube in fron of it). |
Practice: | The student will work in groups to build a three dimensional figure given the side, top, and front views of the figure. The student will discuss which view indicates the number of layers and they will determine from the views, the total amount of cubes it will take to construct the figure. |
Accommodations: | More advanced students will be given the top view of a three dimensional figure that will include the number of layers under the top cube. With this information, they will determine how to build the three dimensional figure. |
Checking For Understanding: | Students will draw and label the front, top, and side views of a given three-dimensional figure. |
Closure: | Ask students to tell what they learned in the lesson. What was interesting in the lesson. What was hard to do. |
Evaluation: | Check students progress by the ability to properly count the number of cubes for each view. Students must be able to correctly identify the number of layers used in the figure. Students should be able to draw or identify the front, top, and side view of a three-dimensional figure. |
