Total Duration:
61 to 90 Minutes
Materials and Resources:
Worksheet copies
Technology Resources Needed:
1 computer with Internet access
LCD projector
Background/Preparation:
Students should have prior knowledge of coordinate planes, how to plot points, and how to calculate area and perimeter.
1.)Show United Streaming Transformations Video [Discovering Math: Geometry; Introduction (2:22), Example 1: Translations (1:22), Example 2: Rotations (1:28)]
Please note that ALL Alabama educators have free access to United Streaming through Alabama Public Television. If you do not have a login or need assistance, you can contact Alabama Public Television for assistance.
2.)Discuss transformations, working examples on the board as a group. If an LCD projector is available, use the following website to assist with group practice. (MathsNet.)
3.)If students have access to computers, allow them to manipulate the website in step 2. If students do not have computer access, explore step 2 as a class.
4.)Distribute the Geometry City worksheet. (see attachment)
5.)Allow students to work on the worksheet as you move through the class to provide guidance. Please note that due to the fact that multiple answers may be correct, no answer key is provided.
6.)Collect worksheets prior to students leaving class so that they may be redistributed to other students during the next class session for checking.
7.)At the next class meeting, have students check another student's work based upon their own understanding of the content (no answer key provided). If a student marks an answer wrong they must be able to justify their decision. Allow approximately 25 minutes for this task.
Attachments: **Some files will display in a new window. Others will prompt you to download.
Informal assessment will be used as the class is viewing the activity on the Internet. As students are working, the teacher should move through the classroom asking students about their work. Students will turn in the worksheet which will be graded for accuracy. In addition, the student's attempt at grading another students work will be taken into account with the worksheet grade.
Acceleration:
Students needing additional material can spend time on the MathsNet website, working problems of increasing difficulty, or students may explore tessellations on the following webquest: Tesselations
Intervention:
Allow students in need of remediation to use foam shapes and a gridded whiteboard to assist in completing the activity. Proximity may also be used for these students, for reassurance purposes.
