InstructionsTry your best to answer the questions above. Type your answers into the boxes provided leaving no spaces. As you work through the exercise regularly click the "check" button. If you have any wrong answers, do your best to do corrections but if there is anything you don't understand, please ask your teacher for help. When you have got all of the questions correct you may want to print out this page and paste it into your exercise book. If you keep your work in an ePortfolio you could take a screen shot of your answers and paste that into your Maths file.

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 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 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 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  A mixture of questions similar to those in levels 1 to 3
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
