Title: Geometry/Polygons
Grade Level: 6-8
Subject: Math and Science
Learner Outcomes: After completion of this lesson the students will be able to identify, draw, and recall the names and definitions of basic polygons. The students will be able to identify regular polygons as well as quadrilaterals.
Duration of Lesson: One fifty minute class session.
Materials: Textbook, paper, pencil, geometry notebook, dry erase markers, as well as approximately 24 computers in a computer lab setting with access to the internet on at least twelve of the computers.
Technology Tools/Courseware:
The students will be using the computer to gain access to the internet
therefore prior knowledge of the use of computers/ lab is recommended.
Some basic skills needed would be word processing and internet searches,
etc.
Teacher Notes:
* Technology coordinator/director of the school needs
to have provided a list of the students that do and do not have written
permission to use or have access to the internet.
* Aides for the special needs/disabled students need
to be available if needed.
Purpose/Introduction:
The students will learn basic geometric terms and concepts as stated by
the instructional goals and objectives 6.31 (draw, compare, and contrast
the following quadrilaterals: parallelogram, rectangle, square, rhombus,
and trapezoid along with the following polygons: pentagon, hexagon,
octagon, decagon, and dodecagon), 6.32 (classify and compare line segments,
angles, and polygons), and 6.41 (measure real objects in order to
develop the formulas for perimeter and area; determine
the perimeter and area
of a triangle, square, rectangle, parallelogram, and irregular figures
given the appropriate measures), that will assist them in composing a geometry
notebook that will be used throughout the middle school years. The
students will search internet sites both in the computer lab and at home
that will assist them in developing this notebook.
Procedures: 1. The students will first learn the importance and need in completing a geometry notebook. 2. The students will then be given a copy of the terms (polygons) that need to be defined and drawn according to the state IGO's. These terms will be placed in a three ring binder( geometry notebook). These terms should be mastered at the sixth grade level. 3. The students will be divided into partners or they may wish to work alone. The students will search internet sites that will assist them in completing these definitions( polygons). A great site that will aid in this assignment is -- Geometry 4. For review and closure of lesson- students will be shown flash cards of various polygons and asked to raise their hand to respond. The students may also be asked to come to the board and draw polygons. For class discussion and homework the students may be asked to identify objects, objects in nature etc. that would be considered a pentagon, octagon, rectangle etc.
Modifications: some modifications to this class session may need to be made. For those students not permitted to use the internet books and other resources will be available for those students to complete their assignment/notebook. Peer helper/buddies will be assigned to those special needs students. University interns, participants, and tutors will be made available to assist in the computer labs.
Enrichment Activities: For those students that need to be challenged -- "stumping problems of the day, and pentagon puzzles will be available. Those students may also wish to use some of their time going to or locating sites on the internet pertaining to geometry. Some real challenging and interesting sites are: A Gallery of Interactive On-Line Geometry and Geometry Math League
Evaluation/Assessment:The students will be evaluated and assessed based on effort, and completeness. The students should all meet satisfactory marks based on the fact that they will be guided through the lessons as well as having books and other resources made available to them besides the computer.
