Phase:
After/Explain/Elaborate
Activity:
This learning activity should be completed at the end of a geometry unit or after a lesson on symmetry.
Pose this real-world problem to the students:
I have decided to renovate my kitchen at home. I love stained glass windows and would like to put a stained glass window above my kitchen sink window. I need your help in designing my stained glass window. I like things to be symmetrical in my house, so you will need to make sure your design has at least one line of symmetry.
Show the students a few examples of stained glass windows. You can use the following link or provide your own examples: stained glass windows.
Students will work collaboratively in a small group or with a partner and use the virtual manipulative link to design their symmetrical stained glass window. They can use any of the manipulatives on this link or you might want to limit them to using the pattern blocks only. Students will print their design on a color printer or print it in black and white and color it.
Assessment Strategies:
Each stained glass window design must be symmetrical and have at least one line of symmetry. Students should be able to identify the line of symmetry.
Advanced Preparation:
Teachers will need to visit the virtual manipulative link prior to the lesson to familiarize himself/herself with it.
Students should already be proficient in finding lines of symmetry.
Each group of students will need access to a device with Internet access.
Variation Tips (optional):
You can differentiate this activity according to ability level by making higher level students create a design with two or more lines of symmetry.
