Each **UNIT STUDY** includes suggestions of books to **READ**, ideas to **WRITE**, crafts to **CREATE**, more to **EXPLORE**, snacks to **ENJOY** and other ways to **LEARN** about a specific topic! To read more about the concepts behind my **UNIT STUDIES**, read **this**.

If you find it handy to have a simplified printable of these suggestions, you can find one, along with several free printables, **here in the FREE Pi Day Unit Study Printable Pack**.

Otherwise, read on for a more detailed version with links embedded!

**INTRO: **I have to admit that I have never {as a kid, classroom teacher or homeschool mom} celebrated** PI DAY. **I never even knew it was a thing until a few years ago when I saw something about it on FaceBook. But, as my son has been slugging his way through Algebra and Geometry this year, I decided it was high time we had some **PI DAY** fun around here!

**READ: Happy Pi Day to You by Bonnie Worth **is a rather fun Cat-in-the-Hat book and the perfect way to start your **PI DAY UNIT STUDY**! It’s in the classic Cat-in-the-Hat style with silly rhyming and funny images but also pertinent facts! These books are marketed as a way to “introduce beginning readers to important basic concepts about the world we live in.” Personally, I find them to be a great way to introduce older kids to more complicated concepts in an easy-to-read style. Especially, when you use the mini Book Companion Pack found in the **FREE Pi Day Unit Study Printable Pack, ** kids of several ages and levels can use this book as a great intro to **PI DAY.**

**Sir Cumference and the Dragon of Pi by Cindy Neuschwander** is part of a clever math series for kids. This math adventure is centered around a quest to rescue Sir Cumference by solving a math riddle with a magic number {that just happens to be** PI**!}

**Might I Interest You in a Piece of Pi? by Miftees** is simply a book of **PI** puns. Fun and funny!

**It Happened One Pi Day by Eric Schmidt** is an interesting approach to helping people {kids included} memorize the first 600 digits of **PI**. I personally have no interest in checking this off my bucket list but the concept is cool and it does make for an intriguing visual aid for how infinite **PI** really is.

**How to Bake Pi: An Edible Exploration of the Mathematics of Mathematics by Eugenia Cheng **is something geared more towards adults and more math-minded teens and covers many more math topics than just **PI** but, for those who want to expand their learning beyond what is found at a kid-level, this is actually a fun and clever read.

**WRITE: The FREE Pi Day Unit Study Printable Pack** includes three different writing activities.

This page just asks kids to make a list of circle-shaped objects.

This next page allows the kids to write as many **PI** facts as they can inside the lined circle.

And this third page is a bit more fun and engaging. It asks kids to write three full **PI** facts but then to write .14 of another fact. That last partial fact is then used as a way to see if anybody can figure out the rest of it!

**LEARN: **If you don’t have access to any of the books mentioned or if you are a mama like me who tends to “plan” short notice, no worries! I’ve got ya covered with this **Pi Day Fact Pack**. It’s simple and to the point but fun with a few ways to look at the most important facts of **PI **along with a few activities to cement the concepts. It’s not free but with discount code HappyPIDay, it’ll cost less than $3.14!

**CREATE: **This **Sidewalk Chalk Pi Activity **not only teaches all about **PI**, it disappears in the rain and doesn’t need to be stored! Gotta love that!

This free **Pop Art Pi Page** is super cute and involves just coloring a whole bunch of circles! Younger kids can do it in a simple fashion while older kids could definitely turn it into a work of {pop} art!

But my absolute favorite way to explore PI in a creative way is this **PI in the Sky Cityscape**! Not only does it allow kids to see the actual digits of **PI**, it allows each kid to take the number as far as they want. Plus, it can be done super simple with graph paper and colored pencils or watercolors can be used to turn it into a real piece of art!

**ENJOY: **What to eat for **PI DAY** seems pretty obvious to me: **PIE**! But, I suppose you could make things a little more well-rounded, ha ha ha, and serve circular food all day long!

Pancakes or Eggos for breakfast would be fun!

Lunch could be either uncrustable sandwiches or something served on pita bread. Both would be great with sliced cucumbers on the side.

Dinner would need to be pizza, of course!

And, then pie for dessert!

**EXPLORE: **{You may want to start your PI exploration by printing out this **free visual aid****.**}

Legos are a family favorite around here but we usually use them just to create elaborate Star Wars ships but when I saw the idea to build **PI** out of Legos, I knew we needed to give it a go! It’s really simple. You just need a **written/printed version** of the number **PI**, a baseplate and several square Legos. Some call it a 3-D Cityscape of PI. Others call it a Pi Graph. We just called it hands-on fun and a great visual representation of **PI**!

**Here is a link** to an **easy hands-on activity for nearly all ages**. It shows how to easily explore **PI** with string.

And **here is a link** to a much more** complex hands-on way to explore** **PI**. It is geared for older kids and will take more time but it allows for a concrete understanding of diameter, **PI** and circumference.

**This link** takes you to the annual **Pi Day Challenge**. It does require you to sign up but the process is quick and simple and then gives you access to some very cool but challenging online **PI**-related puzzles.

If you have an early learner who wants to join in on the **PI DAY** fun, here are a few **simple Pi Day activities **for them. They’re more circle-related than focused on **PI**, but still fun for the little ones!

There are loads of free videos that cover the topic of **PI**. **Here** is a super quick {less than two minutes} video that showcases pies to teach about **PI**.

**Brain-Pop** has one that lasts 3 minutes and 14 seconds {so clever of them.}

And,** here’s** the best one, in my opinion. It’s from TedEd and does a great job of explaining the history of **PI** and how we still use it today…and all under 4 minutes.

But, if you want to take this **PI** thing well beyond simple circles, check out this **Your Life in Pi video**. It’s mind-blowing!

You’re so sweet, thanks! Have a Happy Pi Day!
