Triplets

Find as many sets of three numbers
as possible which add up to 34

26 15 5 28
34 2 5 14
25 23 3 6
4 24 27 29
They don't add up to 34

Click three numbers above that add up to 34. How many different sets of three numbers adding up to 34 can you find? For this activity the order matters (so 1+2+3 would be a different triplet to 3+1+2 for example). You can earn a Transum Trophy if you can find 30 triplets. Do not use a calculator.

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?

Roman Numerals Quiz

You may understand our number system better by learning about another number system. A basic knowledge of Roman numerals will allow you to complete level one of this self marking quiz. Beyond level one will require a little more!

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

"This interactive activity is the pupil version of the whole class lesson starter for 10th December. As well as doing this activity individually it is also worthwhile to do it as a class. As Morriss (Montgomery High School) comments, 'We spend 5 mins individually and then gathered our answers together and got 16 as a class! We really enjoyed this task and got pretty competitive between ourselves and the rest of the Schools that commented!'."
