Comment recorded on the 18 September 'Starter of the Day' page by Mrs. Peacock, Downe House School and Kennet School:

"My year 8's absolutely loved the "Separated Twins" starter. I set it as an optional piece of work for my year 11's over a weekend and one girl came up with 3 independant solutions."

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."

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.

#### Roman Numerals Jigsaw

This is a wonderful activity for someone who does not know Roman numerals. By completing the activity an understanding of the symbols develops and a great sense of achievement is enjoyed.

## 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.

"True or False Level 3 has a lot of ambiguous statements that could be true, false or sometimes be true! For example, the external angles of a REGULAR hexagon are all 60 degrees each making the statement true wheras in the case of an IRREGULAR hexagon, this is not the case necessarily - making the 'sometimes option' applicable. Could you post the solution to this please as I'm pulling my hair out (what little I still have)! Many thanks.

Transum: Steve, thanks so much for your comments and I hope you still have some hair left! You are right, an irregular hexagon does not necessarily have all of its exterior angles equal so that statement would go into the 'sometimes' column. I would like to encourage you to subscribe as the answers are available for subscribers (see above)."

"I just cannot find a solution for x such that 5/x=x
It is in the "sometimes true" category

Transum: Hello Nick,
Beginning with $$\frac{5}{x} = x$$
Multiply both sides by $$x$$ then find the square root of both sides.
Does that help?
