Did you know…Among the digits of pi currently known, the concentration of each of the digits 0-9 are pretty close to equal. However, in the first 30 places of pi’s decimal expansion, there is a digit is completely missing?  Which digit is it?

Spark your math thinking!

1. Set up your math mini spark recording page: #17: Pi Numbers

2. Below you will see the first 98 digits of pi.  Record the number of times each digit appears.  Which digit is not used in the first 30 places?  Record your discovery on your recording page.

3. Take this Pi Day trivia quiz  If you use a website to find an answer, make sure to note that on your recording sheet.

4. Memorize 100,000 digits of pi using this site:  http://www.geom.uiuc.edu/~huberty/math5337/groupe/digits.html  OK…that might be a little extreme, but try to memorize at least 30 places. If you can do 30 already stretch it further.

Circles are EVERYWHERE, and wherever there are circles, there’s math to be done!

Spark your math thinking!

1. Set up your math mini spark recording page: #16: Discover Circles
2. Read this circle fact page. Record 3-5 ideas on your recording page.
3. Find circles in your environment and snap some pictures.  Make a Pic Collage (or use another app of your choice). Add the finished project to your recording sheet.

4. Get a ruler. Snap a picture of a circle that you have found with a ruler going through the center This is measuring the diameter of the circle.  Calculate the circumference of the circle by taking pi (3.14) times diameter.  C = πd. Record your math and the answer on your recording page
5. Read the following steps to see how you can get to Pi!

Step 1:  Measure the diameter of a circle.  I used the top of my QT cup in the picture below. I measured the diameter as 11.5 cm.

Step 2:  Measure the outside of the circle (circumference) with a string (I used a piece of making tape folded in half because I didn’t have a string handy).

Step 3:  Measure the string.  I measured the circumference of my QT lid as 36.5 cm.

Step 4:  Divide the circumference by the diameter (36.5 divided by 11.5).

I got 3.17391304.  Not too bad!

5. Do steps 1-4 with your own circle. Record all of the math on your recording page.

10 squared = 100

The number of centimeters in a meter = 100

The number of sides on a square multiplied by the quantity of the number of letters in the alphabet take away one = 100

55+45 = 100
