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 = 7

4y - x = 13

xy - 10 = 2

180 - 2x + y = 178

20x - 3xy = 24

x2 + y = 13

10x - y2 = 14

y2 - x2 = 19

x2y + 13 = 49

x2y2 - 2x = 138

x2y3 = 576

x! + y = 10

5(x + y) = 35

3y รท x = 22

"I think that having a starter of the day helps improve maths in general. My pupils say they love them!!!"

Comment recorded on the 26 March 'Starter of the Day' page by Julie Reakes, The English College, Dubai:

"It's great to have a starter that's timed and focuses the attention of everyone fully. I told them in advance I would do 10 then record their percentages."

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.
