Did you know that pi is an irrational number that never repeats or never ends? Today in math class, we learned all about the famous pi! We read a story about Sir Cumference and his son, Radius. Then we discovered pi for ourselves by measuring the circumference and diameter of different size circles, then found the ratio (circumference divided by diameter). Every time, our calculations were close to 3.14, which is the approximation of pi! Then we learned how pi is used to find the area of a circle (pi r squared, pie are not!). We went outside and drew "perfect" circles with chalk and string, then we found the area of each circle by measuring it's radius, squaring that number, then multiplying that product by 3.14159.
The best part of the day was enjoying some pizza "pie" and dessert pies! We got to have lunch in the classroom and watch a video about the history of pi. It was an educational (and yummy!) day!
