  1. Quadrilaterals Presented by: The Mathematics and Science Center

  2. What is a Quadrilateral? A quadrilateral is a polygon with four sides. In other words: a four sided shape. http://mathinscience.info

  3. Where can quadrilaterals be found? • Art • Architecture • All around us http://mathinscience.info

  4. What shapes do you see? The Aleph by Marjorie Mikasen http://mathinscience.info

  5. Switzerland Architecture http://mathinscience.info

  6. Richmond, Virginia http://mathinscience.info

  7. Complete the Quadrilateral Hunt • How many quadrilaterals can you find? • What different types of quadrilaterals can you find? • Make sure you include all of the quadrilaterals. http://mathinscience.info

  8. Turn to page two in your packet and complete the chart as you follow along. http://mathinscience.info

  9. What is a parallelogram?

  10. A parallelogram is: A quadrilateral with opposite sides parallel and equal http://mathinscience.info

  11. What is a Rectangle?

  12. A Rectangle is: A parallelogram with four right angles. http://mathinscience.info

  13. What is a rhombus?

  14. A Rhombus is: A parallelogram with four equal sides. http://mathinscience.info

  15. What is a Square?

  16. A Square is: A parallelogram with four right angles and four equal sides. http://mathinscience.info

  17. What is a Trapezoid?

  18. A Trapezoid is: A quadrilateral with only two sides parallel. http://mathinscience.info

  19. Group Work Directions: • Given a set of quadrilaterals, first match each quadrilateral to its correct name. • Next, measure the lengths of the sides and the angles of all of the quadrilaterals and record your findings in the Property Table (p.3 packet). • Using your Property Chart match each specific quadrilateral with one property. • Write your findings on the Property Match Up worksheet (p.4 packet), and be prepared to also place your findings on a class chart. http://mathinscience.info

  21. Venn Diagram Directions: • Complete the Venn Diagram located on p.5 of your packet. • Write the name of each quadrilateral in one section of the diagram (excluding trapezoid). • Please write in pencil in case you need to change your answer. • Think about which shapes have the most properties while you are deciding where the shapes belong. http://mathinscience.info

  23. Directions for Artwork • Tie three pieces of yarn end-to end. Short-Medium-Long. • Tie one end of the yarn around one stick closest to the middle. • In a clockwise direction,wrap the yarn around the next stick once, then go to another stick and repeat. • When you are out of yarn or out of space, tie the end of the yarn to a piece of yarn that is already secure. • After your artwork is complete, answer the questions on the Exploring Your Artwork worksheet (p. 5 packet)
