Triplets

Find as many sets of three numbers
as possible which add up to 32

12 15 11 14
32 8 3 14
11 9 9 12
10 10 13 15
They don't add up to 32

Click three numbers above that add up to 32. How many different sets of three numbers adding up to 32 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.

You might also enjoy the Magic Square Puzzle.

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?

"I think this is a brilliant website as all the students enjoy doing the puzzles and it is a brilliant way to start a lesson."

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!'."
