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 28 September 'Starter of the Day' page by Malcolm P, Dorset: "A set of real life savers!! Comment recorded on the 1 August 'Starter of the Day' page by Peter Wright, St Joseph's College: "Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities. |
Each month a newsletter is published containing details of the new additions to the Transum website and a new puzzle of the month.

Factorising - Factorise algebraic expressions in this structured online self marking exercise.
Level 1 - A quadratic equation presented in a factorised form.
Level 2 - Two terms where the unknown is a factor of both.
Level 3 - Three terms where the squared term has a coefficient of one. The roots are integers.
Level 4 - Three terms where the squared term has a coefficient other than one and the expression factorises.
Level 5 - Quadratic equations that factorise after being rearranged.
Level 6 - The difference between two squares.
Level 7 - Three terms and the roots are not necessarily integers.
Level 8 - Mixed questions on solving quadratic equations
Exam Style Questions - A collection of problems in the style of GCSE or IB/A-level exam paper questions (worked solutions are available for Transum subscribers).
More Algebra including lesson Starters, visual aids, investigations and self-marking exercises.
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.
See the National Curriculum page for links to related online activities and resources.
Answers can be typed in as decimals or fractions but not mixed numbers. For example the answer of \(1.2\) can also be typed in as \( \frac{6}{5} \) but not as \( 1\frac{1}{5} \). This due to limitations of the software used to check your answers. Note that the mixed numbers option would be acceptable in examinations.
Use the forward slash / when typing in fractions.

"Be great if we could enter fractions using the slash e.g. 1/2.
[Transum: Great idea Lisa. The fraction input capability has been activated, Use the forward slash / when typing in fractions. Mixed numbers however will not be recognised so please type those as improper fractions.]"
