The number at the centre of the red shape can be changed by using the radio buttons above.

Level 1

Repeatedly drag the red shape onto yellow cells to change their values.

The objective is for nine to appear in all of the yellow cells.

The cell onto which the red shape is dropped is increased by the number at the centre of the red shape.

The cells which are adjacent to the targetted cell, both horizontally and vertically, are each increased by one.

The yellow cells increase in modulo 9.

The level 5 challenge is made up of nine random numbers. It may not be possible to find a solution depending on what these numbers are.

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?

"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.
