Have students draw an everyday quadrilateral object on graph paper, such as a camera or cell phone. Students should then graph the coordinates on a separate sheet of paper. Have students exchange coordinates without first revealing the object. Students should graph their partner's coordinates and see if they come up with the correct object. Remind students that although these objects are three-dimensional, their representations will be two-dimensional.
Using graph paper, students should draw a quadrilateral of their choice. Have them graph it several times making it bigger or smaller each time but maintaining the scale so while it grows or shrinks, its shape and scale remain the same.
Students can be creative making quadrilateral-shaped animals on graph paper. Have students create their animals out of multiple quadrilaterals, so the legs are shaped from quadrilaterals, the body is shaped from more quadrilaterals and so on for the tail and head. Students should outline all the quadrilaterals that make up the animal. Display these projects around the classroom to reinforce learning.
Provide students with a variety of materials for them to build quadrilaterals of various shapes. You might give the students straws, string, clay, pegboard, rubber bands, or cardboard. Students should label each shape and indicate what makes it a quadrilateral. Ask students to share their creations with the class and describe how each was made.
