What a great "Pi" Day it was today!
We tried to eat only round things for our meals...
made, measured, and decorated pies...
and noted all the wonderful circular objects around us!
Here is one of our mini-pies, as we were finding the diameter (Action shot... the ribbon moved as my daughter snipped it...):
Here we are finding the circumference of the pie:
Here's where the magic starts to happen... We used the diameter-length ribbon and figured out how many fit across the circumference-length ribbon:
 |
| I had my daughter mark a dot showing where the length of the diameter-length ribbon fit, as we moved it across the circumference-length ribbon. We counted it out together and found that it fit just about THREE times! |
To extend her thinking even further, I let her use my wedding rings to try the same experiment, but let her do most of the process on her own...
  |
| The same was true... The circumference was about three times longer than the diameter! |
I'm hoping that for the next few days, circles are noted everywhere, and this experiment is reproduced often! Who says math is boring and difficult...? I believe that there is ALWAYS a way to make it fun!!!
