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 = 1

2x + 3y = 18

5x - 2y = 12

4y - x = 13

xy - 10 = 2

180 - 2x + y = 178

20x - 3xy = 33

x2 + y = 13

10x - y2 = 14

y2 - x2 = 7

x2y + 13 = 49

x2y2 - 2x = 138

x2y3 = 591

x! + y = 26

5(x + y) = 35

3y รท x = 4

"Thanks very much for this one. We developed it into a whole lesson and I borrowed some hats from the drama department to add to the fun!"

Comment recorded on the 1 May 'Starter of the Day' page by Phil Anthony, Head of Maths, Stourport High School:

"What a brilliant website. We have just started to use the 'starter-of-the-day' in our yr9 lessons to try them out before we change from a high school to a secondary school in September 2007. This is one of the best resources on-line we have found. The kids and staff love it. Well done an thank you very much for making my maths lessons more interesting and fun."

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.
