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 17 November 'Starter of the Day' page by Amy Thay, Coventry:

"Thank you so much for your wonderful site. I have so much material to use in class and inspire me to try something a little different more often. I am going to show my maths department your website and encourage them to use it too. How lovely that you have compiled such a great resource to help teachers and pupils.
Thanks again"

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."

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.

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.

Currently the greatest number of points earned in the last month for this level (Level 1) has been achieved by Castlette2 with 116 points on Sunday, June 29, 2025. Can you beat that? If you can make sure you claim a trophy because that is how good scores are officially recognised.

116 points

Example

Suppose I am thinking of the word METRE

You have to try and gress what my word is.

For your first guess you may type in AOMRE

When you have finished typing the tiles will change colour. The colours are the clues:

Example

Now have another guess at my word. Use the clues that you have been given.

You will earn points for guessing my word correctly. When you have earned enough points you can claim a trophy.

Words are cosen randomly from the database of words that might be used in a mathematics lesson. It is possible that a word you have already guessed pops up for a second outing.
