Draw an irregularly shaped polygon on the tile paper transparency. Lead a discussion guiding students to find the area of the irregularly shaped polygon. Ask a student to cover the figure with the colored transparency tiles. Ask students to find the area of the figure. Draw other irregularly shaped polygons, and allow volunteers to find the area using color tiles.
Students are to use square tiles to find the area of the seven irregularly shaped polygons.
About 20 two-centimeter square tiles of various colors for each student, pictures of the animals and objects in the story, one 8x12 or similar size of construction paper for each student, Pezzettino 3. Read the story Pezzetino to the students pausing periodically to show and discuss the pictures and objects in the story. Distribute a picture of one of the objects or animals from the story to each student. Assist students in finding the area of their object or animal by counting the squares. Distribute additional pictures of animals and objects from the story for students to find the area.
