Geometric Glances

Anne Brandon
Escambia County Schools

Description

Students capture pictures of geometric shapes with cameras and use geometric vocabulary to describe the pictures.

Objectives

The student given a verbal description, draws and/or models two- and three-dimensional shapes and uses appropriate geometric vocabulary to write a description of a figure or a picture composed of geometric figures.

Materials

-Overhead projector
-Clear geometric overhead shapes
-Polaroid film and camera
-Pictures of buildings taken from magazines
-White drawing paper
-Pencils
-Clipboard
-Marking pens
-Geometric shape blocks

Preparations

1.Gather materials for activity:
- geometric shape blocks for students
-clear geometric shapes for overhead
-Polorid cameras and film
2. Cut out pictures from magazines of buildings and homes that show geometric shapes.
3. Divide class into groups of four or five students.

Procedures

1. Ask students to list the characteristics of each of the following geometric shapes; square, rectangle,circle,hexagon,and triangle as shown on overhead.

2. Display magazine pictures of buildings, tape to chalk board or pass out copies to students.

3. Ask students if they recognize any geometric shapes in the pictures.

4. Ask the students to describe and locate the geometric shapes.

5. Tell the students they are going to become -Geometric Glancers.-

6. Students will be divided into groups of four to five students and sent out to take pictures of geometric shapes as they see them in and around the school.

7. Students should take turns taking pictures and record the location where the picture was taken. Students should list all geometric shapes represented in the pictures they took.

8. Students remaining in the classroom may draw pictures of buildings including geometric designs.

9. Ask another group of students to try to draw pictures of buildings without using any of the geometric shapes discussed.

10. Compare the pictures with geometric designs included and those without geometric shapes.

Assessments

Students identify, locate, and name the geometric shapes found in their Polaroid pictures and drawings. The student uses correct geometric vocabulary, for example; I see a square in the window of the building or a triangle shape in the design of roof. The geometric vocabulary, triangle,rectangle, square,hexagon and circle, should be used in the students' descriptions of the pictures taken.

Students also compare their two sets of drawings -the set drawn with geometric design, the other set drawn without specific geometric design. When comparing their pictures they should use the words: triangle, rectangle, square, hexagon and circle in their comparisons. For example; I see a square window in your picture, and an irregularly shaped window in my picture. This is a formative assessment.

Extensions

This activity could be extended into another class period if needed for all participants to take pictures and participate in class discussion.
