Why don't Muslims have paintings, drawings, and statues of Muhammad?
This lesson is very informative and FUN for your students. The PowerPoint explains how Muslims came to believe that images of Muhammad are inappropriate and shows how they beautify their mosques without using human images in their stained glass windows, designs, and architecture.
The informational part of the PowerPoint is the first 29 slides. The remaining 21 slides guide your students step-by-step in making their own simple tessellations. I've done this several times with 6th graders, and they LOVE it!
After students are comfortable with the simple hexagon tessellation, you can turn them lose to make their own designs using the hexagon pattern of one of the other six included patterns.
This is a great lesson for helping students appreciate differences between their own culture and those of others.
And did I mention that it is FUN? :)
