Connecting Rules

Here are some equations that are true when x=3 and y=4 but there is at least one mistake. Click on the ticks and crosses to show this piece of work correctly marked.

x + y = 7

x - y = -1

y - x = 4

2x + 3y = 18

5x - 2y = 12

4y - x = 19

xy - 10 = 2

180 - 2x + y = 186

20x - 3xy = 24

x2 + y = 13

10x - y2 = 14

y2 - x2 = 7

x2y + 13 = 49

x2y2 - 2x = 138

x2y3 = 576

x! + y = 10

5(x + y) = 35

3y รท x = 4

"We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much
Best wishes from Inger Kisby"

Dominoes Puzzle

A wonderful puzzle involving all 28 pieces from a set of dominoes. Can they be arranged in seven squares such that the number of dots along the sides of the squares are equal to the given totals?

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.
