We continued our exploration of snowflakes as they relate to geometry. We began by completing our notes about the geometric figures: hexagons, trapezoids, and equilateral triangles. To watch today's notes, go to: Snowflake Geometry Day 2.
Once we completed the notes, we created snowflakes. Each student was given a template to use. I found the templates at http://www.daves-snowflakes.com/patterns.html Each template began as a hexagon, was folded on a line of symmetry to form a trapezoid, was folded to form a rhombus, and finally folded to form an equilateral triangle. Now, the students cut away the black areas. Each snowflake was attached to a sheet of black construction paper:
Finally, the students had to write critically about the snowflake. I did not want to read about "fun" or "cool" or "awesome." While I love hearing this words about my class, they are not mathematical words that describe our learning. So the writing prompt was:
Explain the geometry found in your snowflake by describing at least three geometric attributes.
I have taken the snowflakes and descriptions up to display them on lockers. Snow in Texas!
