Welcome Back! Snowflake Geometry

It is the first day back after a two week vacation and it snow we didn't get any snow while we were out.... so what better way to pique interest in math than by focusing on snowflakes?!

Snowflakes are actually very mathematical!  

Our goal today was that the students would be able to generate geometric definitions using critical attributes of a 2-dimensional figure. 

We began by reading the book:

This is the true story of Wilson Bentley who had a passion for studying snowflakes.  He even invented a way to photograph them in order to share the beauty of snowflakes with the world!

After reading the story, I showed a short video about Snowflake Bentley that showcases the photographs he began taking in the early 20th century.  The images are pretty amazing!

Finally, we began to focus on the geometry of snowflakes by working with the fact that most snowflakes are hexagonal.  We defined a hexagon by using its critical attributes (sides, vertices, angles, lines of symmetry, parallel, etc.).

At this point, we ran out of time. We needed to spend time on a Fifth Grade Builder to get back into the swing of things and continue our spiral review.
