Method
1: Distribute to
each student in the class a three by five card containing the name of a
quadrilateral. The teacher then makes a statement, such as "This
quadrilateral has diagonals congruent." Students whose cards contain
the name of a quadrilateral possessing this characteristic raise their
card.
Method
2: Divide the class into six groups. Each group
represents a type of quadrilateral. Prepare a large sign with the
name of the quadrilateral for each group to display. As in method 1,
the teacher makes a statement, such as "This quadrilateral has two
pair of opposite sides congruent." The group whose
quadrilateral possess that characteristic raises their sign. Method 3: Choose a panel of student volunteers. Give the student volunteers cards with the name of a quadrilateral on each card. The remaining students then ask one question each (directed to a specific student volunteer) in an attempt to identify which quadrilateral each volunteer represents. (Obviously, students cannot ask "What quadrilateral are you?") After the questioning is complete, the students write down their answers. Have prizes for the winners. In this activity, students develop their problem solving skills as well as their knowledge of the properties of quadrilaterals.
