As we get well into the summer term here are the next sets of mental arithmetic questions for Years 4, 5 and 6. The Year 4 questions concentrate on fractions and decimals, together with a little bit of counting, addition and subtraction. To answer the fraction questions correctly children will need a knowledge  to know what fraction of a pound is 10p and what fraction of a metre is 10 cm. Luckily the metric system makes these answers quite easy. The Year 5 questions are all about doubling, halving and multiplication. Children are expected to be able to double any 2-digit number and halve any even 2-digit number 'in their heads'. Questions 5, 6 and 7 look at multiplying multiples of 10 which they should find straightforward if times tables are known. The Year 6 questions follow a similar pattern, but with harder numbers. For example, multiplying 6.55 by 100 just needs a good understanding of place value as each digit moves two places to the left. There are also a couple of questions finding half of decimal fractions which could prove quite tricky. Go to Year 4 mental arithmetic Go to Year 5 mental arithmetic Go to Year 6 mental arithmetic
