Paradox

Drag four yellow statements into each of the brown rectangles.
Make sure you don't create a paradox!

All of the statements in this rectangle are true

Only three of the statements in this rectangle are true

Only half of the statements in this rectangle are true

Only one of the statements in this rectangle is true

The sum of 3 and 4 is 7

The product of 3 and 9 is 27

The sum of 2 and 8 is 10

The product of 9 and 12 is 108

The product of 4 and 3 is 12

The product of 7 and 5 is 35

The sum of 9 and 4 is 14

The product of 12 and 2 is 26

The sum of 1 and 7 is 9

The product of 5 and 3 is 18

The sum of 7 and 1 is 9

The product of 3 and 6 is 24

Congratulations

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?

"This triangle starter is excellent. I have used it with all of my ks3 and ks4 classes and they are all totally focused when counting the triangles."

Comment recorded on the 28 May 'Starter of the Day' page by L Smith, Colwyn Bay:

"An absolutely brilliant resource. Only recently been discovered but is used daily with all my classes. It is particularly useful when things can be saved for further use. Thank you!"

Featured Activity

Connect 4 Factors

Connect 4 Factors

A mathematical version of the popular Connect 4 game based on getting four numbers with a common factor in a line. Fun for one, two or a whole class of pupils.

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.
