Plinko Probability

The Quincunx, commonly known as the Galton Board, is a statistical device invented by Sir Francis Galton in the 19th century to demonstrate the central limit theorem and the normal distribution. It consists of an upright board with a series of pegs arranged in a triangular pattern. Small balls are dropped from the top of the board, and as they descend, they bounce off the pegs in a random fashion, either to the left or right. At the bottom of the board are a series of bins where the balls collect. Over time, as many balls are dropped, they tend to form a distribution in the bins that resembles a bell curve or normal distribution. The Galton Board visually illustrates the concept of randomness and how individual random events can collectively produce a predictable pattern. It has been used extensively in educational settings to teach principles of probability and statistics.

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 25 June 'Starter of the Day' page by Inger.kisby@herts and essex.herts.sch.uk, : "We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much Best wishes from Inger Kisby" Comment recorded on the 9 October 'Starter of the Day' page by Mr Jones, Wales: "I think that having a starter of the day helps improve maths in general. My pupils say they love them!!!"		Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month. The newsletter is then duplicated as a podcast which is available on the major delivery networks. You can listen to the podcast while you are commuting, exercising or relaxing. Transum breaking news is available on Twitter @Transum and if that's not enough there is also a Transum Facebook page.

This is the numerical version of the extremely popular internet sensation Wordle and UK TV quiz show called Lingo.	Numeracy "Numeracy is a proficiency which is developed mainly in Mathematics but also in other subjects. It is more than an ability to do basic arithmetic. It involves developing confidence and competence with numbers and measures. It requires understanding of the number system, a repertoire of mathematical techniques, and an inclination and ability to solve quantitative or spatial problems in a range of contexts. Numeracy also demands understanding of the ways in which data are gathered by counting and measuring, and presented in graphs, diagrams, charts and tables."

Go Maths Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths main page links to more activities designed for students in upper Secondary/High school.
