Arrange the given statements in groups to show whether they are always true, sometimes true or false.

## False

Angles in a triangle add up to 180o

x + 5 = 10

A shape with four sides is a rectangle.

The radius is equal to the diameter

x + 5 = 5 - x

5 ÷ x = x

x2 > x

An angle greater than 90o is obtuse

"I am an NQT and have only just discovered this website. I nearly wet my pants with joy.
To the creator of this website and all of those teachers who have contributed to it, I would like to say a big THANK YOU!!! :)."

Comment recorded on the 3 October 'Starter of the Day' page by Mrs Johnstone, 7Je:

"I think this is a brilliant website as all the students enjoy doing the puzzles and it is a brilliant way to start a lesson."

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.

#### Triangle Solver

This simple calculator will work out the lengths of the sides and the size of the angles of any triangle given thee particular pieces of information.

## 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?
