Geometry, Teacher\'s Edition

(Axel Boer) #1

  • Identify how to classify shapes on a coordinate grid.


II.ProblemSolvingActivity-QuadDesign



  • This is a creative design activity.

  • The students are going to need colored pencils, crayons, markers, rulers, large blank sheets of paper.

  • The task is to create a design that has each of the seven figures in it.

  • Students need to create a color key to identify the seven figures in the design.

  • They can include any other shapes/color that they would like, as long as the seven figures are in the design.

  • Here are the figures that must be in the design: parallelogram, rhombus, rectangle, square, kite, trapezoid,
    isosceles trapezoid

  • Allow students the entire class to work.

  • Tell students that creativity does count in the activity.


III.MeetingObjectives



  • Students will identify and classify a parallelogram.

  • Students will identify and classify a rhombus.

  • Students will identify and classify a rectangle.

  • Students will identify and classify a square.

  • Students will identify and classify a kite.

  • Students will identify and classify a trapezoid.

  • Students will identify and classify an isosceles trapezoid.


IV.NotesonAssessment



  • Check each design to be sure that all of the seven figures are in it.

  • Be sure that there is a key that is clear and easy to read.

  • Include color and creativity in the assessment of each student’s work.

  • Create a bulletin board to display student work.


Using Parallelograms


I.SectionObjectives



  • Describe the relationships between opposite sides in a parallelogram.

  • Describe the relationship between opposite angles in a parallelogram.

  • Describe the relationship between consecutive angles in a parallelogram.

  • Describe the relationship between the two diagonals in a parallelogram.


II.ProblemSolvingActivity-ParallelogramExploration



  • Walk the students through this activity.

  • Allow time for students to share their responses after each step of the activity.

  • Students will need paper, pencils and rulers to complete this task.

  • First, ask the students to draw two sets of intersecting parallel lines on a piece of paper.

  • When finished, ask them to label the verticesA,B,C,D

  • Ask “What do you notice about this figure?”

  • Some students may recognize the parallelogram right away.
