## Time to Celebrate

Are your students doing anything special for Day? After two months with no significant break, we are going stir crazy. We need a day off — and what better way could we spend it than to play math all afternoon?

If you need ideas, here are some great pages:

**Printable Pi Day Sudoku**

And another, and another, because with Sudoku, you can’t do just one! And here’s yet one more.**Pi Day ideas & links**from the Math Forum**Pi Day at Mrs. Burke’s Math Page**

Including*Are You Smarter Than a 5th Grader?*Version 1, Version 2, and Pi Day Jeopardy. These PowerPoint games test your students’ knowledge of math and -related trivia. Older students may prefer the online pi trivia game.**Visualizing Pi**

## History of Pi

**A Brief History of****The Story of Pi****Things that equal Pi****The “Jewish” or “Bible” value of pi**

Does the Torah really say that = 3?**A Chronological History of Pi with Developmental Activities in Problem Solving**

I would love to use a lesson like this. Unfortunately, it is full of typos and far from user-friendly. Has anyone written a better version?**Archimedes’ method of exhaustion**

I’ll approximate this with my MathCounts kids, using squares and hexagons. Archimedes worked up to a 96-gon, but that is beyond us. High school students may enjoy another Archimedes puzzle.**MacTutor’s History of Pi**

Follow the adventures of from II Chronicles 4 to 20th century Germany, including the still-open question: Is “normal”?**How Pi Was Almost Equal to Three in Indiana**
