  1. Quadrilateral Unit A Five Day Quadrilateral Unit: Includes; Activities, Guided Power Point, Task Cards, In depth thinking, and an assessment

  2. 5 Day Geometry Unit • Includes the following: • Slides 3-23: Day One: Slides 3-18 includes a guided geometry lesson in which different types of quadrilaterals and their properties are introduced. Slides 19-23 contain a Quadrilateral booklet for students to keep. As you are discussing the quadrilaterals and their properties, students can record them and practice drawing them in their own quadrilateral booklet. To use, cut down the dotted line in the middle of the page and staple together to make a book. • Slides 24-31: Day Two: Property sort. Students will break into partners or small groups. They will take the 8 polygons on slides 26 and 27. They will then cut out the pictures and attributes of the polygons on pages 28 and 29 and place them under the correct polygon on pages 26 and 27. They will also have a reflection piece where they will write about their findings. • Slides 32-46: Day Three: Task Cards. Students will break into small groups or partners and complete the geometry task cards on the quadrilaterals and polygons. A recording sheet and answer card has been included. • Slides 47-51: Day Four: Comparing and contrasting quadrilaterals. Students will cut out quadrilaterals and choose 2 to compare and contrast. They will then take a venn diagram card and compare the 2 using the venn diagram. They will complete at least 5 diagram cards and the writing/reflecting activity at the end of day 4. • Slides 52 and 53: Geometry Assessment: Students will review the terms and quadrilaterals and then take an assessment on what they have learned.

  3. Quadrilaterals Day 1: Guided lesson. Use the power point presentation on slides 3-17 to introduce quadrilaterals. While you are introducing the quadrilaterals, have students take notes and complete their quadrilateral book on slides 18-22.

  4. Quadrilaterals E.Q.: What are the properties of quadrilaterals?

  5. Drag the examples of quadrilaterals to the example side and the Non-Examples to the Non-Example Side. Examples Non-Examples

  6. Examples Non-Examples Answers

  7. With your group or partner, discuss what you notice about these examples

  8. They all have Four Sides They all have Four Corners (Angles) Some have 4 equal sides Some have 2 sets of equal sides What else can you add to the list?

  9. Shapes that have four sides can be grouped into one big category: Quadrilaterals

  10. Record in your Quadrilateral Book Trapezoid Properties: Only ONE set of parallel sides. When proving if a figure is a trapezoid, it is necessary to prove that it has 2 sides that are parallel and 2 sides that are not.

  11. Record in your Quadrilateral Book Parallelogram Properties: Has Two sets of parallel sides. Two sets of sides that are the same length. Opposite angles are the same.

  12. Record in your Quadrilateral Book Rectangle Properties: 4 Right Angles, 2 sets of parallel sides, 2 sets of sides are the same length

  13. Record in your Quadrilateral Book Rhombus Properties: 4 equal sides, 2 sets of parallel sides

  14. Record in your Quadrilateral Book Squares Properties: All sides are equal, 2 sets of parallel sides, All angles are right angles.

  15. Based on our observations and properties of our quadrilaterals, discuss with your partner or group: Is it possible for a square to be a rectangle? Why do some quadrilaterals look so much alike? Is a rectangle a rhombus? Can some shapes be called other names?

  16. Place the shapes into the correct column: Parallelograms or Trapezoids Square Trapezoid Rhombus Parallelogram Rectangle

  17. Quadrilaterals?

  18. Journal or Summary Explain the properties of quadrilaterals. Choose 2 quadrilaterals. Draw and label each. Then, discuss how these two quadrilaterals are alike and different.

  19. My book of Quadrilaterals A quadrilateral is any four sided figure.

  23. Choose Two Circle the quadrilaterals Compare and Contrast Two Quadrilaterals. Include a sketch of each quadrilateral in your diagram. _________ _________ Alike _________________________ ____________________________________________________________ Different _______________________ ____________________________________________________________

  24. Day 2: Property Sort Review quadrilaterals from day one. Briefly introduce pentagons and hexagons. Break students into partners. Have them cut the cards on slides 25 and 26. Students will read the properties on each card and place them under the correct shape on slides 23 and 24.

  25. Polygons and quadrilaterals E.Q.: What are the attributes of polygons? How can I sort polygons according to their attributes?

  26. Quadrilateral Characteristics Name_____________

  27. Write about it Choose two shapes that have similar characteristics. Reflect: Why can different geometric terms be used to name the same shape? ___________________________________ ___________________________________ ___________________________________ ___________________________________

  28. Day 3: Task Cards Review quadrilaterals from day one. Break students into partners. Have them complete the task cards. Record them on the answer sheet. When they finish, have them write in their journal.
