I did this kaleidoscope lesson years ago and it didn't go the way I wanted it to. I decided to do it again because it works so well with radial symmetry. I even have a class set of kaleidoscopes for my students to look through.
Only this time I changed it out a bit and stressed certain factors that needed to be in place. I also started the lesson by having the students do a mandala which I blogged about here.
I modeled for my students by tracing a wedge shape on a planning sheet (the wedge was 1/6 of the circle). I explained we would use letters on the wedge, either a name, initials or a word. The top and bottom of the letters need to touch the edges of the wedge. I believe this was part of what made it successful along with the fact that the circle was divided into only 6 equal parts.
They traced, flipped, traced, flipped until the circle was filled in.
I think they came out GREAT!!
Thanks for Reading!
