Roll, Drop, Draw: A Fun Math Adventure

Celebrating the Magic of Numbers on March 14

By TINA KHATRI | March 12, 2026

Imagine a person who didn’t learn math from a textbook but said equations were “written on his tongue” by a goddess. That was Srinivasa Ramanujan. Without formal training, he arrived at Cambridge and turned math upside down.

He once saw number 1729 on a taxi and instantly noted it was the smallest number expressible as the sum of two cubes in two ways. To him, numbers weren’t just symbols; they were a living language. On March 14 (3/14) every year, we celebrate the contributions of mathematicians and the number $\pi$ (Pi), which connects math and the calendar.

Come have a slice of Pi. Square your worries away with cinnamon rolls!

1. Food Activity: Infinite Cinnamon Spiral

Cinnamon rolls are edible Archimedean spirals, where the curve moves away from the center at a steady pace.

Materials: 1 pack ready-to-use dough, butter, cinnamon/sugar, icing.
Math Prep: Roll dough into long, flat rectangle; measure length with ruler.
Experiment: Spread butter/cinnamon and roll tightly from one end to the other.
Observation: You’ve transformed a 1D line into a 2D area circle. Measure the diameter!
Bake: Slice and bake at 180°C (350°F) for 15 minutes. Draw a $\pi$ symbol with icing.

Math Connection: Shows spirals, area, and how circles store linear measurements.

2. Stick Drop: Buffon’s Needle

Discover $\pi$ by dropping sticks onto lined paper and measuring probability.

Materials: Large paper, ruler, 20–30 toothpicks (same length).
Setup: Draw parallel lines double the length of a toothpick apart.
Action: Drop all toothpicks randomly from about 1 foot above paper.
Calculation: Divide Total Drops $\div$ Crossed Lines. Result should be close to 3.14!

Math Connection: Teaches probability, geometry, and the physical reality of $\pi$.

3. Craft Activity: Pi-Line Skyline

The skyline is built by the "DNA" of a circle – $\pi$ itself. Write the code:
3, 1, 4, 1, 5, 9, 2, 6, 5, 3, 5, 8, 9, 7, 9

Materials: Graph paper, colored markers.
Construction: First column = 3 blocks high; Second = 1 block; Third = 4 blocks, and so on.
Art: Color each building differently and add a celestial background!

Math Connection: Explores numbers, sequences, visual patterns, and bar graphs.
