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 5 April 'Starter of the Day' page by Mr Stoner, St George's College of Technology: "This resource has made a great deal of difference to the standard of starters for all of our lessons. Thank you for being so creative and imaginative." |
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. |

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 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. The Go Maths main page links to more activities designed for students in upper Secondary/High school. | ||

Which Transformation? - This is an easy exercise to begin with asking you to recognise some very simple transfomations.
Level 1 - Reflect a shape in a given line
Level 2 - Translate a shape by a given vector
Level 3 - Rotate a shape about a given point by a given angle
Level 4 - Enlarge a shape from a given point by a given scale factor
Level 5 - Transform a shape by a given matrix
Level 6 - Mixed questions without diagrams
Level 7 - Describe the transformation from the diagrams
Exam Style questions are in the style of GCSE or IB/A-level exam paper questions and worked solutions are available for Transum subscribers.
There is a printable worksheet to go with this activity.
Finally try Blow Up, a clallenge to find all the points that could be the centre of enlargement of a shape if the image does not go off the grid. Great fun!
Click on the points where the gridlines meet to select a point. When you have selected the number of points required to complete the diagram a 'Check' button will appear.
You can select the 'Show' button if you don't know how to do a question. Refresh the page when you think you understand and try for yourself.
You can earn a Transum trophy for each level if you get at least nine questions correct.
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.

"If you having difficulties when you get to Level 3 Rotations you are not alone. Rotations are difficult without using tracing paper to help. I stumbled across this video on YouTube in which George Turner shows the windmill method:
