Building a Model of a Dream Home

Three-Dimensional Shapes

AUTHOR: Terry Sayre, Tigard, OR

```

OVERVIEW: In this activity, students will identify what shapes architects use to build houses. Students will then explore these shapes by building a model of their “dream” home.

OBJECTIVES: The student will

1. identify how architects use shapes.

2. work cooperatively to create and execute a plan to build a model of a home.

3. create a cone, cube, rectangular prism, and cylinder.

4. use at least three, three-dimensional shapes in their dream home.

RESOURCES/MATERIALS: patterns for three-dimensional shapes, construction paper, tag board, scissors, glue.

ACTIVITIES AND PROCEDURES:

Introduction:

1. “How many of you know what an architect does? What is the difference between architecture and an architect?”

2. “What shapes do architects use to build things? Are those three-dimensional or two dimensional?”

3. “Today, each of you are going to join a team of other architects. Together, you will design a model of your dream home.”

Lesson Plan:

1. Before you begin this lesson facilitate an activity that creates cooperative groups of 2-4.

2. Team builder exercise.

a. One piece of paper will be given to each cooperative group.

b. Students will be instructed that they will have only two minutes to write down as many geometric shapes as they can.

c. Each student will write the name of only one geometric shape and then pass the paper to the next student.

d. The game ends when the time expires.

3. Demonstrate how to make cones, rectangular prisms, cylinders and cubes from the photocopied patterns. Have students practice making their own.

4. Discuss with the class that they will be acting as architects and that it is very important for architects to have a plan.

5. Give students enough time to come up with a plan for their model dream homes. They must incorporate at least three, three-dimensional shapes.

6. Encourage the class to do their personal best when “erecting” their structure. Creativity is a positive thing. So, if students decide to make something else instead of what you asked, be flexible!

7. Mount their dreams on tag board. Display them for all to enjoy.

Closure: Examples of some questions that could be asked.

“What did you learn from this activity? What did you like best about it? Who can tell me what subject we are studying? What do architects do? What are three- dimensional shapes?”
