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 2 April 'Starter of the Day' page by Mrs Wilshaw, Dunsten Collage,Essex:

"This website was brilliant. My class and I really enjoy doing the activites."

Comment recorded on the 14 September 'Starter of the Day' page by Trish Bailey, Kingstone School:

"This is a great memory aid which could be used for formulae or key facts etc - in any subject area. The PICTURE is such an aid to remembering where each number or group of numbers is - my pupils love it!
Thanks"

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.

23 or Bust

A game involving mental arithmetic and strategy for two players or one player against the computer. It is possible to beat the computer but you need a well thought out strategy.

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."

Secondary National Strategy, Mathematics at key stage 3

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.

"Knowing the names of the polygons is only the start. Each shape has its own properties which define it. There are families of shapes and some shapes can be identified with more than one name. The next step is to show your knowledge of Polygon Properties with our interactive matching activity."

"It has recently come to my knowledge when attempting one of your activities under Topic - Geometry - Activities - Polygons - Rotational Symmetry there is an error in this task.
If I am not mistaken all shapes have a rotational symmetry of at least one, however in this task it shows shapes with a rotational symmetry of one are considered none.
This little mistake may be enough to make someone fail their exam or fall one excellent credit short of endorsement in this wrong teaching. Therefore I recommend you change it before an unfortunate student suffers that fate."

"Dear Luke,

Thank you so much for taking the time to make a comment about rotational symmetry.

Firstly I must say that sometimes in Mathematics everyone does not agree on certain definitions. For many years the UK defined a billion as 1012 while the US defined it as 109. Some people believe that zero is a member of the set of natural numbers while others do not. I’m afraid rotational symmetry may also attract mixed opinions.

According to all of the online references and textbooks I have seen there is no such thing as rotational symmetry of order one. As Wikipedia states: "Note that '1-fold' symmetry is no symmetry (all objects look alike after a rotation of 360°)".

If you have a reference that disagrees with this way of thinking please let me know.

I really would appreciate hearing any further comments you may have about the activities on the Transum website.

Best wishes "
