The key focus of mathematics in Year 3 is to ensure your child is confident and increasingly fluent working with whole numbers and the four operations + – x ÷, including their knowledge of place value and number facts, for example 15 + 3 = 18, 3 + 15 = 18, 18 – 3 = 15, 18 – 15 = 3. They will calculate mentally and begin to develop efficient written methods, working with three-digit numbers and to calculate with fractions. They will continue to develop their reasoning skills, explaining how they approached problems, analysing similarities and differences when working with shapes. By the end of Year 3 they should have memorised and be fluent in their 2, 3,4,5,8 and 10 multiplication tables.
