Class Opener – Day 24 – It’s Snowing in October!

After last week’s experience with Sierpinski’s Triangle, I was eager to see other math landmarks my students had encountered. Knowing that our next unit will be on sequences and series, it seemed like a perfect time to share this:

Many students identified “the Snowflake” immediately, and I filled in the “Koch Snowflake” gap.  Soon, our room was filled with ideas of fractals and self-similarity. We grabbed markers, and started drawing on our desks.

How many sides does this have?

What is its perimeter?

Tomorrow, we will look at patterns and develop explicit formulas for them. Today’s opener planted some seeds I hope to sow during tomorrow’s discussion.
