Happy 𝛑 Day! What better day to celebrate our favorite, familiar, fantastic irrational number? This 𝛑 Day we are bringing you a 𝛑-centric approximation activity, a detailed explanation of why this activity approximates 𝛑, and a special bonus math problem and solution (in case you want to spend your 𝛑 Day doing math, math, and more math :) ).

At BEAM Discovery the 100 Problem Challenge encourages students to work collaboratively; this past summer students earned a badge for completing a problem from this list of intriguing, puzzle-like problems. We can’t offer you a badge, but this one is pretty satisfying to solve, so give it a whirl!

Fill in each of the hexagons below with a positive integer so that the number in each hexagon is equal to the smallest positive integer that does not appear in any of the hexagons that touch it.

BEAM National plans to reach thousands of students from low-income and historically marginalized communities nationwide.

Try your hand at a Problem of the Week from BEAM Discovery (our summer program for rising 7th graders)! The Problem of the Week gives students a chance to explore interesting math outside of their classes, either on their own or in collaboration with others.
