    Geometry Outdoors -- Out Teach

    Geometry Outdoors -- Out Teach

    Overview

    Students will use their knowledge of geometric shapes to find real world examples outdoors.

    Background for Teachers

    Out Teach logo

    In 3rd grade students are expected to classify and sort 2 and 3 dimensional solids which includes cones, cylinders, spheres, triangular and rectangular prisms and cubes based on attributes.

    Key Vocbaulary

    • Faces

    • Edges

    • Vertices

    • Cone

    • Cylinder

    • Sphere

    • Triangular prism

    • Rectangular prism

    • Cube

    Guiding Question

    How do attributes help you classify these geometric shapes?

    Engage

    Play a game where students have to guess the geometric shape you are talking about.

    Ask: I am thinking of an object that has 4 Faces, 6edges and 8 vertices. Who am I?

    Ask: I am a 2 - dimensional shape with 3 edges and 3 angles. Who am I?

    Explore

    Before beginning this portion have students create a simple table in their journals.

    Label the first column "FIGURE" the second column "NAME OF FIGURE" and the third column "REAL WORLD EXAMPLE" so student pairs can record their findings.

    Allow them to move around the outdoor classroom for 20-25 minutes.

    Management Note: (Sample): Ensure students understand the boundaries of the area they are exploring, review expectations and make sure they listen for the signal to return to the gathering space.

    Ask questions to assess what they know

    Ask: How many face, vertices or edges?

    Ask: What is the name of this 3 dimensional figure?

    Ask: Do you see any 2 dimensional figures that makes this up?

    Differentiation Note: If students that need additional support consider giving them a reference chart or a partner with a deeper knowledge of geometry.

    For students who need an additional challenge have them sort the objects they found.

    Explain

    As pairs share consider questions to address misconceptions or build understanding.

    Ask: Do any shapes share the same attributes?

    Ask: How could these shapes be classified?

    Ask: Which shape has the greatest/least number of (edges, vertices, faces)

    Elaborate

    Classify and compare shapes found indoors with those found outdoors.

    Evaluate

    Use tables in journals to assess.

    Quick write idea: Which 2 dimensional shapes can be joined to create a 3 dimensional shape.

    Extensions and Connections

    Students can create "Who am I?" game for another class.
