I’m always a big fan of making learning fun, so Cindy Neuschwander’s books are a perfect fit for me.  Today’s lesson centered around “Sir Cumference and the Dragon of Pi – A Math Adventure”.

Materials List

  • Book, Sir Cumference and the Dragon of Pi by Cindy Neushwander
  • A seamstress’s measuring tape
  • A round table and other round objects including a pie
  • Dress up costumes for knights and princesses, queens and kings
  • A calculator

We started off dawning our royal robes and gathering at our kitchen table, which just so happens to be round.  Together we read the story out loud.  Afterwards we talked about the math concepts in the book and used the tape measure to determine the radius, diameter, and circumference of our objects.  Everyone took a turn with a difference circular object to reinforce the lessons learned, terms, and practice measuring.  My oldest son took on the pseudo role of Merlin the magician, using the “magic number”, aka pi, to calculate the circumference more quickly than the rest of us could measure, and double checking our answers.  This drove home the idea that math is a helpful tool.  To top things off of course we had to have pie/pi.  My middle child has been busy cultivating her culinary skills this summer and baked us a tasty blueberry crumble pie, using the last of the blueberries we picked last week.   This of course gave us an opportunity to discuss fractions and division too as we cut and served the pie.  All in all a very memorable (and tasty) lesson!
