Earthmerlin Posted March 2, 2018 Share Posted March 2, 2018 Anyone have any interesting, fun, educational, and edible ideas for Pi day? I'd like to get my 8 year old introduced to this concept/day. Thanks! Quote Link to comment Share on other sites More sharing options...
TX Native Posted March 2, 2018 Share Posted March 2, 2018 (edited) Well, for edible, I would bake a pie. Then find the area and circumference of the pie using the pi formula. Edited March 2, 2018 by TX Native 2 Quote Link to comment Share on other sites More sharing options...
Kebo Posted March 2, 2018 Share Posted March 2, 2018 You could eat as many circle shaped food items as possible in a day and work the math for each of them. Pancakes, apples cut transversely, carrot coins, a pie, etc 1 Quote Link to comment Share on other sites More sharing options...
Earthmerlin Posted March 3, 2018 Author Share Posted March 3, 2018 Well, for edible, I would bake a pie. Then find the area and circumference of the pie using the pi formula. LOL, yeah pie for sure. I also read the same for pizza too--a double pie-tastic idea! 1 Quote Link to comment Share on other sites More sharing options...
daijobu Posted March 4, 2018 Share Posted March 4, 2018 (edited) Make sure he understand what pi actually is: the ratio of the circumference of a circle to its diameter. It's cool, because no matter which circle you choose, the circle around a tomato sauce can, the circle of a hula hoop, or anything in between, if you measure around its diameter circumference it will be roughly 3 times the length of it's diameter. Try it. (That's your pi day activity right there.) I was carpooling one of my dd's friends and she was proudly reciting the digits of pi. But when I asked, she couldn't tell me what pi was. So much for regular school. Edited March 4, 2018 by daijobu 2 Quote Link to comment Share on other sites More sharing options...

Earthmerlin Posted March 4, 2018 Author Share Posted March 4, 2018 I found a 'cutie pi' t-shirt as well! There are a couple kids' books we'll read. Of course we'll get our hands on a few circle objects & do the math. I found a few crafty activites as well but we'll see how much I can pack into the day.

Gil Posted March 4, 2018 Share Posted March 4, 2018 (edited) Make sure he understand what pi actually is: the ratio of the circumference of a circle to its diameter. It's cool, because no matter which circle you choose, the circle around a tomato sauce can, the circle of a hula hoop, or anything in between, if you measure around its diameter circumference (the outside part) it will be roughly 3 times the length of it's diameter. Try it. (That's your pi day activity right there.) I was carpooling one of my dd's friends and she was proudly reciting the digits of pi. But when I asked, she couldn't tell me what pi was. So much for regular school. Fixed. This year, the boys are racing to memorize the most digits of pi (with the goal being the first 314). The prize is $0.01 for every digit that is memorized correctly. So, if they get all 314, they get a whopping $3.14. We'll do the whole pi-themed dinner at home. Pi-themed cut outs and circle shaped foods. Edited March 4, 2018 by Gil 2 Quote Link to comment Share on other sites More sharing options...

El... Posted March 4, 2018 Share Posted March 4, 2018 All my ideas revolve around eating. We'll do some calculating, too. I have a book called Big Ideas for Small Mathematicians which has some neat ideas. It was hard to explain pi before Dd knew how to multiply by a decimal or fraction. She's been eating pie on pi day for a while without fully understanding, but this is the year of understanding for her, I think. 2 Quote Link to comment Share on other sites More sharing options...
Farrar Posted March 4, 2018 Share Posted March 4, 2018 There are a lot of things where you make Pi necklaces or chains - each digit is a different color. It's to emphasize the lack of pattern with the digits and/or help with memorization. I have mixed feelings about those, but for crafty kids, I think they're fun. You could read the Sir Cumference books. 3 Quote Link to comment Share on other sites More sharing options...

You don't need to understand the particulars of the numbers to learn about pi. That's the beauty behind the whole idea. I explore the idea of pi with students K-12 by using a ribbon, markers, a ruler and paper. FIRST: Teach the idea of circumference and diameter. Have kids trace several circles on paper or cardboard. Have them color the circumference in one color, and diameter in another. SECOND: Get a bunch of circular containers. Use a ribbon to measure the diameter, mark that in color on the ribbon. Then use another piece of ribbon and wrap that around the containers circumference, mark that in color on the ribbon. Compare the lengths of ribbon. The diameter should fit in the circumference three times, with a little bit left over each time. 3 Quote Link to comment Share on other sites More sharing options...

Yes, I think it was more a failure of how to teach on my part, and Ds6 will get a lot out of this year's fun, too. Thank you for the ideas!!

You could read the Sir Cumference books. I have seen the bracelets. We shall see if it piques her interest. There's a 'pi city' whose buildings' heights are based on the numbers of pi. We are for sure going to read Sir Cumference. There's another title re: pi, circumference, and diameter but the title escapes me now. I believe it's by the same author?

Junie Posted March 6, 2018 Share Posted March 6, 2018 We eat a lot of pie on pi day: Pizza pie for lunch Chicken pot pie for dinner Fruit pie for bedtime snack I might look for a quiche recipe for breakfast this year. :) 1 Quote Link to comment Share on other sites More sharing options...
ScoutTN Posted March 6, 2018 Share Posted March 6, 2018 Apple pie, pumpkin pie, pecan pie, chocolate pie, lemon meringue pie... Chx pot pie, beef pot pie (we often do this one mexican, with a cornbread crust), pizza pie... For breakfast (in case the apple pie option doesn't suit you) , we make egg pie, a veggie and cheese quiche with a sausage crust. 1 Quote Link to comment Share on other sites More sharing options...
