Radius and Diameter Link:

4th graders embarked on an exciting mathematical journey! They dove into the world of circles, exploring the fascinating radius and diameter link.

03

A Circular Adventure Begins!

Our young mathematicians brought an array of circular objects from home, turning our classroom into a hub of geometric discovery. From clocks ⏰ and plates to oranges and coconut shells ?, the variety was astounding!

Measuring Up the Fun!

Armed with measuring tapes and rulers, our budding scientists got to work:

1. Measuring diameters of various objects
2. Calculating radii (half the diameter) ✂️
3. Recording measurements in centimeters

The excitement was palpable as they discovered that radius is always half the diameter, and diameter is twice the radius!

05

Real-World Math in Action

Our clever kiddos even measured the diameters of dosas ?, muruku ?, and coconut buns ?! Talk about making math deliciously relevant!
