Geometric attributes (such as sides and corners) provide descriptive information about an object's properties.

Essential Questions

How does geometry better describe objects?



About the Math

At this level of understanding, students need to recognize shapes and begin to notice their properties. Formal definitions of the shapes is not necessary. Recognizing that some shapes of three sides, four sides, no sides is an important observation.

Rich Tasks for Multiple Means of Engagement, Expression, and Representation (UDL)

Rich Problem:

What's My Shape? - Activity 7.2: Teaching Student-Centered Mathematics Grades K-3 (195).
For further Instructional Activities from this text, refer to Activity 7.6 (207), Activity 7.12 (213), Activity 7.18 (217)

Teaching Student-Centered Mathematics, Grades K-3: Chapter 7, Geometric Thinking and Geometric Concepts (186-220)

Develop spatial sense by connecting geometric shapes to students’ everyday lives. Initiate natural conversations about shapes in the environment. Have students identify and name two- and three-dimensional shapes in and outside of the classroom and describe their relative position.

Ask students to find rectangles in the classroom and describe the relative positions of the rectangles they see, e.g. This rectangle (a poster) is over the sphere (globe). Teachers can use a digital camera to record these relationships. Hide shapes around the room. Have students say where they found the shape using positional words, e.g. I found a triangle UNDER the chair.
