L7 – WWW – Y2 Add and Subtract Two-digit Numbers and Ones

Support your Year 2 pupils in building core calculation skills with this interactive Maths Resource Pack, focusing on adding and subtracting two-digit numbers and ones. Designed to meet the National Curriculum, this resource helps children develop strategies for efficient mental and written calculations with practical examples and problem-solving tasks. Through clear teaching slides and worked examples, pupils are guided to add and subtract ones from two-digit numbers using number lines, partitioning, and place value knowledge. For example, they learn that 46 + 3 can be solved by counting on, while 58 – 6 can be tackled by counting back or using number bonds. Independent activities encourage children to practise using a range of strategies, represent problems visually, and explain their reasoning. A plenary recap helps consolidate key skills, ensuring pupils can apply their knowledge confidently in different contexts, including word problems.
