Run Light Show Clear Instructions
There are many wonderful patterns in Pascal's triangle and they make excellent designs for Christmas tree lighting. Choose a number pattern from the dropdown box above, set the timing and colour then add it to the instructions for the lighting display. Press the Run Light Show button to see your creation.
During your display each light will stay on for one second so setting a light to come on every 1 second effectively means that light stays on for the whole display time.
Patterns chosen further down the dropdown list may overwrite some of the lights in the patterns chosen higher up the list.

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 11 January 'Starter of the Day' page by S Johnson, The King John School: "We recently had an afternoon on accelerated learning.This linked really well and prompted a discussion about learning styles and short term memory." Comment recorded on the 2 May 'Starter of the Day' page by Angela Lowry, : "I think these are great! So useful and handy, the children 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. 

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 MathsLearning 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.

"Creating this activity was the most interesting project I have tackled for ages. I discovered many more patterns in Pascal's triangle than I thought were there. Creating the algorithms and formulas to identify the hexagons that need to light up for any chosen pattern was a great example of Maths in action and a very satisfying experience. Here is the first light show I created on completing the project: First Light Show. I'm sure you can do much better. Have fun!"
