Cons

Recent reviews

This app simulates a Galton board, which is a pegboard that you drop marbles through and they bounce off the pegs and fall into bins. It shows a natural appearance of the famous Bell curve from statistics, and addresses a whole bunch of other math stuff like triangular numbers and Pascal’s triangle in a natural and interesting way. Beautifully done, could be a wonderful teacher’s aid or homeschool resource.

Love this product. The first time I saw a Galton Board was the the Science Museum in Flushing, NY. My mind was blown. I am so glad that a proper digital version was created. It would be awesome if Index Fund Advisors, Inc. could bring the physical product back.

This app was great for helping me understand the concept of bell curves for a class I’m taking this semester! I’m glad it’s out there for students like me :)
