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 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College:

"Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson. Keep up the good work"

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!

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 page is an alphabetical list of free activities designed for students in Secondary/High school.

Description of Levels



Level 1 - Angles at a point

Level 2 - Angles on a straight line

Level 3 - Vertically opposite angles

Level 4 - Mixed questions

The mixed questions provide a recap of levels one to three and introduce some algebra. This level offers an opportunity for a little more problem solving rather than simply applying a rule.



Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don’t yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.

Angles at a point

The sum of the angles that fit around a point is 360°.

a° + b° + c° = 360°

Angles at a point

Angles on a straight line

The sum of the angles that fit on a straight line 180°.

a° + b° = 180°

Angles on a straight line

Vertically opposite angles

Where two straight lines cross vertically opposite angles are equal.

a = b

Vertically opposite angles
