4.G.2 Compare and classify quadrilaterals by length of sides and types of angles (Include the symbol <ABC) MSA Assessment Limit: Use squares, rectangles, rhombi, parallelograms, and trapezoids. Activity 1 Give students four popscicle sticks to use to create quadrilaterals. Complete the chart that classifies the quadrilateral’s attributes. SHAPE Parallel Sides Congruent Sides Right Angles Parallelogram Rectangle Square Rhombus Trapezoid Activity 2 Riddles Have students use the shapes found on the attached page to sort when solving the riddles. i.e.: 1. I am a quadrilateral with all right angles. Students will find the square. Take this opportunity to discuss how a square is a rectangle. 2. I am a quadrilateral with all sides equal. Students will find the rhombus and the square. Take this opportunity to discuss the differences and similarities between the two shapes. 3. I am a quadrilateral with at least one acute angle. Students will find a parallelogram, rhombus, and a trapezoid. This will lead to a great discussion of the why a square and rectangle are not selected. Activity 3 Give students index cards. On the blank side have them illustrate a quadrilateral in real life (spaces on a checkerboard: square, skyscraper: rectangle, desk top: rectangle, trapezoid table trapezoid, side of a roof of a house: parallelogram, etc.) On the lined portion of the index card, have students write their own clues to describe the quadrilaterals they have drawn on the other side.
