ICT

"Imaginative use of ICT should help engage more learners in the excitement of learning. Borrowing ideas from the world of interactive games, we can motivate even reluctant learners to practice complex skills and achieve much more than they would through traditional means. New technologies can attract new kinds of learners into lifelong learning. Wider access to these more compelling learning experiences will contribute to the ambitions of our Skills Strategy to offer employers better support for skills and training."

Secretary of State for Education and Skills

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.

"Hi There. I feel obliged to question one of your answers there. Surely 9.846 rounded to one decimal place has to be 9.9. The 4 becomes a 5."

"Hi Logan. When rounding to one decimal place you only have to consider the value of the second decimal place. You can ignore the rest of the digits.
To make it clear have a look at the diagram below. You can see that 9.846 is closer to 9.8 than it is to 9.9. Therefore it makes sense to round it to 9.8.
