We have just published the latest sets of mental arithmetic questions for Years 4, 5 and 6. The Year 4 questions are a mixed bag, including relating fractions to decimals, doubling numbers with halves in and some addition problems. Children may not have come across doubling a number such as 24 and a half, which would probably be done in two parts, doubling the 24, and then adding one. It's mainly fractions for the year 5 sets  of questions. Questions such as 'How many sixths are there in one third?' can cause confusion for children and highlights the importance of understanding equivalent fractions. The year 6 questions again look at equivalent fractions and writing fractions as decimals. There are a lot of interesting patterns that can be made from converting fractions to decimals when using a calculator.
