Pi Day – a day set aside every year on March 14th to celebrate the mathematical constant 3.1415 (etc.) is a fun day for math geeks like me. I also think that Pi Day is a wonderful opportunity to get kids thinking about ways in which math can be fun, so today I am sharing some fun ways to celebrate Pi Day with kids – a few days early, so you have time to plan. This year it is extra special, because a sequential time will occur during Pi Day at 9:26:53 following the sequence of pi (you can also celebrate at 9:26:54 if you choose to round up).
Fun Ways to Celebrate Pi Day With Kids
Have you ever tried to visualize Pi? Last year my brilliant bloggy friend Erica wrote a wonderful post about creating Pi skyline art. I thought Erica’s post was cool, but it required a lot of patience, and the image immediately reminded me of Cuisenaire rods, which happen to be one of my favorite math manipulatives. Then I discovered these overhead projector Cuisenaire rods, and I knew they would be even more fun for my Pi Day project! This is a great affordable light table solution for a single child.

The kids spent some time playing with the overhead Cuisenaire rods on the table, because playing with math manipulatives is one the best ways for kids to develop a mathematical instinct! Do you see how Anna is laying the foundation for understanding fractions as she plays with these little overhead pieces on our light table?
Cuisenaire rods are color coded based on how many units long they are. We used the light table Cuisenaire rods because they are a lot of fun and they photograph beautifully, but the wooden or plastic ones work equally well and are the same colors and length. The white squares represent one unit, red two, lime green three, magenta four, yellow five, green six, brown 7, red eight, and blue nine. We didn’t need the orange ten unit piece for this project. You can read the first 23 digits of pi on our light table in the image above (or the identical one at the top of this post): 3.1415926535897932384626. Want more digits? You can find the first 10,000 digits here, which should be enough to keep you busy for a while!
