Grade Level:

WNCP:

Objectives:

Students will be able to describe the characteristics of 3-D objects and 2-D shapes, and analyze the relationships among them.

General Outcome:

Explore and classify 3-D objects and 2-D shapes, according to their properties.

Specific Outcomes:

  1. Explore, classify, and describe 3-D objects according to two attributes.

  2. Observe and build a given 3-D object.

  3. Identify, name and describe specific 2-D shapes such as:

    • Circles
    • Rectangles

Materials:

Activity 1:

Video 2: "Laying out the Canvas" (Glen Anaquod), molding clay.

The following still images from the Glen Anaquod Tipi Raising

  • Semicircle of canvas

  • Rope around the poles

  • Three pins inserted

  • Placing canvas on the structure

  • Completed tipi


Activity 2:

Images from activity 1, geo boards, elastics

Activity:

  1. Let students take a look at the still image called ‘completed tipi.’ Have them describe the tipi. Using molding clay or natural clay, allow students to build a copy of the tipi.

    List the following items on a whiteboard or chalkboard: canvas, poles, pins, and rope. Print off images listed in the materials section. You can show students video 2, which gives a clearer image of the canvas versus the still image.

    Using the images, have the students sort the objects into exactly two groups. What was their sorting rule? Give them a classroom object. Ask them in which group this new object belongs? Have them explain why.

  2. Alternative Idea:

    Have students use geo boards and elastics to create the shapes found in the tipi:

    • Poles, canvas (semi-circle), pins, circle (base of tipi)

    Once the shapes are display on the geo boards, have students sort the collection into two groups and name each group. Have students try another way to sort them. Students should identify each shape as a circle, rectangle, etc.
