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 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School: "What a brilliant website. We have just started to use the 'starteroftheday' in our yr9 lessons to try them out before we change from a high school to a secondary school in September. This is one of the best resources online we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun."

Go MathsLearning 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.

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.
Example:
Angles at a pointThe sum of the angles that fit around a point is 360°. a° + b° + c° = 360° 

Angles on a straight lineThe sum of the angles that fit on a straight line 180°. a° + b° = 180° 

Vertically opposite anglesWhere two straight lines cross vertically opposite angles are equal. a = b
