Today’s date, 22 July written as 22/7 in DD/MM format reminds us of a well-known approximation of the mathematical constant pi (π).

What Is Pi? How did it get a value of 3.14? Let’s explore this using a hands-on activity.

The digital activity below provides a visual way to explore the same idea. It helps learners connect their measurements (of hands-on activity) with a dynamic representation of how pi is formed.

Open the link and follow the instructions in the activity to investigate the relationship between circumference, diameter, and pi.

Note: Try the hands-on activity first to build a strong understanding before moving on to the digital activity.
