**Welcome to Pi day!**

Pi day is March 14 because 3.14 are the first three digits of Pi.

Yes, Pi is a bit advanced for the intended readers of Smiling Dog™ Math books. After all, the first two books of the series cover counting to 9 and adding to 9. Book #3 is on the horizon, and that focuses on adding to 10.

The concept of Pi—the ratio of the circumference of a circle to its diameter (about 3.14159) is still years away for our budding mathematicians.

**Yet, you'll find that Smiling Dog™ Math books plant seeds for the future.**

That's why the NUMBERs love pie. Hmmm . . . or "Yummm . . ."

In fact, Pi, is pivotal to book #2, *Circus Fun! Add Up to 9*. The NUMBERs get into trouble at dinner, and Mom is so upset that the NUMBERs are sent to their rooms without Pie.

No Pie! Unthinkable! What willl they do?

**Here's a Pi Day activity for little ones**

What you need:

- A circular object with straight sides (e.g, cup, pot, mug, etc.).
- Construction paper and a marker to make a small "ruler" the length of the diameter.

Here's what to do:

- Ask, "How many of "these" (the "ruler" the length of the diameter) do we need to go around the (cup) just once?
- It's so unintuitive; the answer will be a fun surprise.
- Now make a second ruler that is 4 times as long as the diameter, and mark each diameter length on that ruler.
- Wrap it round the object.
- Mark where it touches the other end.
- So we need "3 and a bit more" to go around!
- What if we do the same thing with a different size circle? (Remember to make a new ruler each time based on the diameter of that new circle.)
- Wow! The answer is always "three and a bit more."

**Cool! You've just help your child discover Pi.**

Maybe celebrate the new discovery with some pie. My favorite is blueberry with a scoop of vanilla ice cream.

**Happy, Happy Pi Day!**
