Lesson on Special Quads

1. LESSON PLAN
Topic : Geometry
Aim: What are the properties of Special Quadrilaterals?
Grade Level : 9­10
Rationale : In a world where technology is part of our students' every day life, integrating technology in their learning is just a natural
progression. This 2­day lesson is designed to make learning the properties of quadrilaterals, which is a popular topic on the state
Regents, a meaningful and interactive experience with the use of technology. Students will be engaged in cooperative and discovery
learning and play the role of active participants during the entire lesson. Research shows that students who are exposed to an
environment where their visual, auditory and kinesthetic senses are stimulated, and who are made the masters of their own learning,
have more success retaining and understanding information.
Students will be able to :
­ Recognize Special Quadrilaterals based on their shapes.
­ Determine the properties of Special Quadrilaterals based on their sides, angles and diagonals.
­ Establish the existing relationships between Specials Quadrilaterals.
Materials/Technological Tools
• Interactive Smart Board
• Sound files and Video files
• Senteo Response System
• Geometer’s Sketchpad
• Internet
• Computer Lab
• eBoard
• Worksheets
• Pencils
Motivation: As the students walk in, I will be greeting at the door and handing them their individual Senteo clicker. As usual, “Let’s
Get it Started” will be playing on the Smart Board speakers and the Senteo title page displayed. Shortly after, they will begin
answering the real world multiple­choice questions displayed on the next six Smart notebook pages with their Senteo clickers.
Roles: Students will be active participants while the teacher is a monitoring guide.
Pre­assessment: Students will answer six questions where they will have to use their prior knowledge to recognize the Special
Quadrilaterals from the real life images presented to them. Their result will be immediately display on the Smart Board after the last
question, thus giving them instant feedback.
Development: Students will then be counted off from 1 to 6 and assigned a single quadrilateral based on their number. They will
then open their assigned GSP file found on the shared drive, and construct, investigate and report the properties of their figure. On
the 2 nd day, they will group according to their numbers and share their findings. Each group will go on the Smart Board and each
member will demonstrate and fill in a property for their assigned quadrilateral while their classmates are actively listening and taking
notes.
Post­assessment: Students will use the Senteo Response System again to answer a series of 8 questions assessing their knowledge
and understanding of the detailed properties and relationships that were just presented to them. For Homework, students will access
the teacher’s eBoard (iNote) to write a letter to a friend detailing the key points of the lesson according them.
Alternate Post­Assessment (if presentations extend to the bell): For Homework Students will access the teacher’s eBoard
(iNotes) to answer a series of 8 questions assessing their knowledge and understanding of the detailed properties and relationships
that were just presented to them. They will have a deadline to submit their entries. The teacher will then log on to their eBoard and
retrieve their answers.
