What is the Galton Board?

The Galton Board is a 7.5” by 4.5” desktop probability machine. A STEM™ approved product coupled with a STEM™ curriculum, this delightful little device brings to life the statistical concept of normal distribution. As you rotate the Galton Board on its axis, you set into motion a flow of steel beads that bounce with equal probability to the left or right through several rows of pegs. As the beads accumulate in the bins, they approximate the bell curve, as shown by the yellow line on the front of the Galton Board. This hands-on Galton Board allows you to visualize the order embedded in the chaos of randomness.

STEM™ Approved Product

STEM™ stands for Science, Technology, Engineering and Math. STEM™ education integrates concepts that are usually taught as separate subjects in different classes and emphasizes the application of knowledge to real-life situations. The Galton Board is approved for STEM™ educational activities.

"Mark, I have to hand it to you and your team… Galton Board is an amazing and meticulously-designed product. Congratulations!"
