Galton Board 31 x 23 x 11 cm Normal Distribution Model with Pascal's Triangle and Formulas Black Base Teaching Aid
You already have the maximum available quantity in your cart.
The Galton board is a visual model that illustrates how many random events lead to a regular outcome. Small silver balls are released from the upper reservoir through a narrow neck, hitting rows of pegs and randomly deflecting left or right at each peg. In the lower compartments, they arrange themselves into the shape of a bell curve, known in statistics as normal distribution. The transparent board stands in a solid black base with the inscription GALTON BOARD, making the model look great in classrooms, offices, and home studies.
On the front of the board, three formulas are printed that directly relate to the experiment: the binomial probability formula, the binomial theorem, and the normal distribution density formula. Between the pegs, the numbers from Pascal's triangle are inscribed, showing how many different paths a ball can take to reach each position. Below the compartments, the percentages indicating the probability of a ball landing in each column are listed, and a drawn bell curve runs across the compartments for comparison with the results. The entire model measures 31 x 23 x 11 cm, making it easily visible from a distance while fitting on a standard writing desk.

- Contents – Galton board with balls and black base
This model is appreciated by teachers of mathematics, physics, and computer science who wish to demonstrate probability, randomness, and the law of large numbers in a way other than just on a blackboard. It is also suitable for students, analysts, programmers, and anyone working with data who enjoys clever items on their desk. The experiment can be repeated by flipping the board, allowing the balls to return to the upper reservoir and be poured again over the pegs. Each pouring creates a slightly different pattern, but the result always approaches the same curve. The board and base can be wiped occasionally with a dry or slightly damp cloth and should be placed on a flat and stable surface.
The Galton board combines an educational tool, a soothing visual experience, and an original decoration in one item. The printed formulas and numbers from Pascal's triangle connect the experiment with theory, allowing you to see both the formula and its result in the form of a bell curve in one place. The model, standing 31 cm tall on a black base, is a practical addition to classrooms, offices, and studies. It also makes a suitable gift for students, teachers, and lovers of mathematics and statistics who will appreciate an unconventional yet meaningful item.
