Yummy Shapes

Cindy Jacobs

Description

Students identify space shapes and their characteristics. As a fun culminating activity, students identify shapes found in vegetable soup and enjoy!

Objectives

The student describes attributes of three-dimensional shapes using mathematical language (for example, curves, vertices, edges, faces, angles).

Materials

-Space Shape Models(sphere, rectangular prism, pyramid, cube, cylinder, and cone)
-Cans of Chunky Vegetable Soup (enough for one serving per student)
-Crock Pot
-Soup Bowls (Enough for Class)
-Spoons
-Paper and pencils for each child

Preparations

1. Gather materials needed for this lesson.
2. Put soup on in advance so that it will have time to warm up before the lesson.

Procedures

1. Display shape models (sphere, rectangular prism, pyramid, cube, cylinder, and cone). See if students can identify any of these shapes. Discuss the names of each of these shapes. Tell students that they are called space shapes because they are three-dimensional and take up space.

2. Tell students that space shapes have faces, edges, or corners.

3. Explain that faces are flat. Hold up the cube. Tell them to look at the faces on it. Each face is shaped like a square. Ask which shape doesn't have a face? (answer:circle) Ask students to identify the plane shape of faces found on a pyramid? (answer:triangle) rectangular prism? (answer:rectangle) cylinder? (answer:circle)

4. Tell students an edge is a line segment. Ask which of the space shape objects have an edge? (Answer: pyramid, rectangular prism, and cube)

5. Next, tell students that a corner is where three or more edges meet. Ask students to identify which of the space figures have corners. (Answer:rectangular prism, cube, and pyramid)

6. Instruct students to look around the classroom for objects shaped like a sphere, rectangular prism, cube, cylinder, cone, and pyramid. If students have difficulty locating items, have them think of items at home that have these shapes.

7. Pass out paper to students and have them number their papers one through six. Hold up one shape one at a time,and have students identify the name of the shape by writing it on their paper. When through, collect papers for assessment purposes.

8. Last, serve each student a warm bowl of vegetable soup. Have students identify space shapes found in their soup and discuss. They should figure out that beans are shaped like cylinders, peas like spheres, carrots and potatoes like rectangular prisms/cubes, etc. Allow students to eat and enjoy!

Assessments

1. Mastery and non mastery will be informally based on observation of students while identifying and discussing characteristics of each shape. 2. A formal assessment will be based on the student correctly identifying 5 out of the 6 space shapes (step 7 from procedures)correctly.

Extensions

Unifix cubes, K'Nex objects, pipe cleaners,etc. could be used to build three-dimensional space shapes. Given various space shapes, you could have students identify the shapes and then make a column for faces, edges, and corners, and have them identify the number of attributes each shape has.
