” We cannot hope that many children will learn mathematics unless we find a way to share our enjoyment and show them its beauty as well as its utility.” a quote by Mary Beth Ruskai undoubtedly signifies how important it is to check the manner in which math is dealt with in the current era. Mathematics a subject which is equally loved and and hated by many has several reasons for the same. Let us try to improve the way in which math is taught and dealt with so that young minds will start enjoying the beauty of it rather than considering it as a burden. Pi Day is observed on on March 14 (3/14 in the *month/day* format) since 3, 1, and 4 are the first three significant digits of π. Pie approximation day is observed on July 22 (22/7, an approximation of π). In this article let us check the Pi Approximation Day 2023: History, Significance, Quotes and Activities

**History of Pi Approximation Day**

Pi (π) was known and used ancient times approximated for almost 4000 years. The ancient Babylonians also calculated the area of the circle by taking three times the square of its radius which gave the value of pi equals to three. **Archimedes of Syracuse (287–212 BC),** one of the greatest mathematicians of the ancient world was the first person to do the calculation of π. Archimedes tried to show that the value π is between 3 1/7 and 3 10/71.

Pi Approximation day is a observed annually to celebrate the usage of the mathematical constant π (pi). Pie day is observed on March 14 and** Pi Approximation Day is observed on July 22**. **Pie day was founded by Larry Shaw** in the year 1988. On November 2019 United Nations designated Pi day as the International Day of Mathematics.

**Pi Approximation Day 2023 Significance**

Following are few important facts about Pi

- The number
**π**(/paɪ/) is a mathematical constant. - It is defined as the ratio of a circle’s circumference to its diameter
- It is approximately equal to 3.14159.
- It is also referred to as
**Archimedes’ constant**. - Fractions such as 22/7 are commonly used to approximate it.
- Its decimal representation never ends and never settles into a permanently repeating pattern.
- It is known that π is a transcendental number:
- There is no zero in the first 31 digits of Pi
- At position 763 which is also known as Feynman Point, there are six nines in a row
**In 2015, Suresh Kumar Sharma**, a former vegetable vendor from Jaipur, India now a memory coach, set a world record when he successfully**recited more than 70,030 digits of pi**. It took 17 hours to complete the memorization- Johann Lambert proved Pi is irrational in 1768
- As the exact value of pi cannot be calculated, we can never find the accurate area or circumference of a circle.
- The Welsh mathematician William Jones began using the symbol for pi in 1706.
- Lu Chao of China recited 67,890 digits of pi in the year 2005.

**Pi Approximation Day Celebration 2023: Activities**

Listed below are the activities to celebrate Pi Approximation Day.

**1. Circle Art**

Teachers at school can conduct various activities through which the concepts of circle can be explained creatively. Students can be taught the concepts of diameter and circumference through activities. The symbol and importance of Pi can be explained to students.

**2. Bake a PiE**

Families can involve in a fun and learning activity by baking cakes in the shape of circle or pie. At the same time the concepts of circle can be taught to the smaller kids at home.

**3. Memorize Pi Contest**

A contest can be conducted at institutions where in each one can try memorizing the decimal numbers of pie. It will be fun and learning at the same time.

**4. Organize a pizza party for kids**

Elders can organize a pizza party for kids . As pizza takes the shape of the circle, when each part is cut into triangles, the concept of fractions and geometry can be explained to students

**5. Teach Math through fun and learning activities**

We tend to see that majority of students doesn’t like math most of the time cause of how hard it gets later on. But if math is taught through activities and practical learning methods then students may be able to grasp things better. So teachers and elders can try to keep math as engaging and creative as possible

**6. Organize Circle hunt activity at Office or school**

A quick ice breaking activity can be conducted to de-stress the employees when at work by checking for circle shape items around the cabin and calculating the ratio of circumference of the circle to its diameter

**7. Formation of Pi Chain**

Students at school can be engaged in an activity of constructing a pie chain using paper. each circle cut outs can represent one digit or decimal number by representing it in a different color. This will also help in improving the color recognition skills and fine motor skills of the kindergarten students.

**8. Conduct Quiz**

A quiz on mathematics can be conducted online thus encouraging students to learn more about the numbers and values and making it interesting in every way possible

**9. Organize a walk-a-thon of 3.14 miles**

A walk-a-thon can be organised in a community for 3.14 miles thus representing the value of pi. health and fitness can also be highlighted during the event. If fund is raised during the process then it can be donated as charity for the education of students

**10. Conduct free basic mathematics session for the underprivileged**

Check for the locality wherein the students do not get the basic education due to poverty. make a club of friends for this cause and start free sessions on mathematics for the students who does not get the basic right ton education.
