**Vocabulary: ***maths **词汇： 数学*

The UK government has said that from 2014, it will **ban calculators** in **maths tests** for **primary school** children in England.

All 11-year-olds **sit** three maths tests. Pupils are allowed to use a calculator in the hardest of these. A sample question is: "Tickets for a school play cost £2.75 each. Dev sold 23 tickets. How much ticket money did Dev collect?"

Education and Childcare Minister Elizabeth Truss says children are **over-reliant**** on** calculators and that this means they don't have a good **grounding in mental arithmetic** or written arithmetic. She wants all children to be confident with other methods of **addition, subtraction, times tables **and** division** before they start using calculators in **secondary school**.

Research shows that 98% of pupils in England use calculators in primary school classes, compared with an international average of just 46%. At the same time, different research shows that children have become worse at maths in the past 30 years. Ms Truss believes that children are **dependent on** calculators and that's making the problem worse.

Some teaching experts argue there's **a plus side to** using calculators. They say that they are an important **tool** for maths, which children need to learn to use. Christine Blower of the National Union of Teachers, says the ban "will diminish the **skills set **for primary pupils" and cause problems when they need to use calculators in secondary school.

Russell Hobby of the National Association of Head Teachers, says the **advantage** of using calculators is that children can focus on the **maths problem** itself, rather than the individual **calculations** needed to **solve** it.
