Celebrate The Circle On 3/14 With Eureka Math²
Pi day is celebrated on March 14, or 3/14, which recalls the common numerical approximation of pi, 3.14. The day was established to celebrate the mystery, intrigue, and history of the famous constant, π.
The Eureka Math2® team wants to ensure that all students experience the beauty of math—on March 14 and every day. We’d like to share some resources that highlight the beauty of math as well as the exceptional coherence, accessibility, and engagement you'll find in Eureka Math2.

Highlighting the Story of Pi
Math Past
Each module in Eureka Math2 features a connection to mathematical history known as Math Past. Each Math Past allows students to contemplate the mathematical reasoning used by these ancient mathematicians and to make connections to the math they are doing in their own classroom.
You can see how Eureka Math2 celebrates pi in this Math Past example from Grade Level 7 Module 4, as students trace the history of pi and its increasingly accurate approximations, from the ancient Babylonians and Egyptians to Archimedes himself.
Building Foundational Knowledge
Grade Level 1 Module 6 Lesson 13
In Grade Level 1 Module 6, students explore the concept of equal shares with pizza. Students discuss how each share of the pizza would get larger or smaller, depending on the number of people they are sharing the pizza with.
The familiar visual representation of a pizza helps students build enduring understanding by making connections to their own experiences.
Developing Understanding
Grade Level 3 Module 6 Lesson 13
In Grade Level 3 Module 6, students explore perimeter as they outline various shapes with string. They then find the perimeters of these shapes by measuring the string used to outline the shapes.
This lesson demonstrates the use of hands-on learning and manipulatives to support students as they develop the skills to represent mathematical concepts in more abstract ways.
Advancing Concepts of Circles
Grade Level 7 Module 4 Lessons 15
In Grade Level 7 Module 4, students explore the definition of pi. In Lesson 10 they physically measure objects to discover the constant themselves. Then in Lesson 15, students design and test a sprinkler system that uses circular, semi-circular, and quarter-circular regions—a challenge that improves their understanding of the area of a circle.
This video showcases an example of the student experience during this engaging digital lesson.
Going Further with Pi
Grade Level 8 Module 1 Lesson 21
In Grade Level 8 Module 1, students apply what they’ve discovered about irrational numbers and the square root of nonperfect squares to approximate the value of π2. Students build on their prior knowledge of pi and area of two-dimensional figures, all while employing approximation methods that mathematicians have used for centuries.
