There are few math related holidays that carry the excitement of Pi Day, and we want to show you how you can get your class hyped up about this mathematical constant. March 14th, otherwise thought of as 3/14, is the numerical approximation of Pi, and this number has an international fan club ready to unleash their love of Pi tomorrow. It is these math enthusiasts who have provided Pi inspirations, projects, and knowledge that you can share with the students of your classroom.

**Pi, we all know of it, but what is this irrational number?**

Often referred to as one of the strangest numbers in mathematics, Pi is something that sticks with students for the rest of their lives. Even as an adult, you know that the approximation of Pi is 3.14, or 22/7, even if you have no real use for it in your life. Introduced in the middle of the 18th century, this irrational number is a pattern of a specific set of numbers that are randomly distributed in the sequence. Pi is interesting because it never ends, and was named after perimetros, a Greek work for perimeter.

**Pi and musical adaptations**

Pi, is known for being a mathematical constant, but love of this irrational number has been translated into many different forms. For example, this video on YouTube The Sound of Pi: A Musical Collaboration shows what Pi would sound like if the numbers were a musical composition. There are many other music videos on YouTube that include a waltz, and an informational video that shows what Pi would sound like on various instruments. This musical adaptation of Pi is a good way to show the versatility that Pi has in our world.

**Introducing Pi, planets, and many other applications.**

A good way to get students excited about Pi is to show them ways that this number is being used outside of mathematics. Pi is a significant part of the calculations that planetary science uses when looking for new planets that lie outside of our solar system. Pi is also used when scientists want to examine the density of a planet. These are only two of the many uses of Pi in the science field, and according to quantum mechanics, it is suggested that Pi is one of the reasons that the universe is constructed the way that it is,.

**Pi Projects**

One of the easiest ways to celebrate Pi Day is for teachers to plan classroom parties. You can ice the back of cookies with Pi, provide crafts for students to document the numbers in the Pi sequence, or even create paper chains that are labeled with individual numbers.

Get creative and have fun with it because Pi is a sequence that can provide hours of entertainment for your students.

Pi Day is a time to get students excited about science and mathematics with the introduction of the concept of Pi in your classroom. How will you get students interested in Pi?
