Big Idea: Structure Geometry

Enduring Understandings Essential Questions Geometric figures can be described and classified by faces, sides, edges, and vertices. Changing the position of an object does not affect its attributes. Some shapes can be combined to make new shapes. The amount of space inside a shape is its area.

What are the attributes of a shape? What makes a shape congruent? How are plane figures and solid figures related?

What is area?

Bundle Performance Task(s) Provide the students with 2-D and 3-D geometric shapes to examine and identify the attributes. On the performance sheet (see attached), students will record the number of faces, sides, edges, and vertices/corners of each shape. Once they identify the characteristics of each shape, students will write the name of an object in the environment that has the same attributes. (ex. Rectangular prism: 6 faces, 12 edges, 8 vertices-tissue box) With partners, have students use geoboards (online , iPad, manipulatives) to create similar and congruent figures. Each partner will select a different color geoband to use. The first partner will create a shape on the geoboard and the teacher will specify whether partner two will make either a congruent or similar shape on the same geoboard with their color geoband. Students will take turns explaining to their partner why the shapes are congruent or similar. As an extension, 3-D geometric shapes will be put into a bag. One student will reach into the bag (don’t look!) and describe the shape using the vocabulary terms (faces, sides, edges, congruent and vertices) to the other students. Peers will draw the shape as it is described and determine its name. The shape will be shared. Each student will have a turn giving the descriptions. This can be done in a small group or as partners. Show the drawing described and then record the name of the actual shape. See performance task template at the end of the bundle.
