Addition and subtraction within 10 - Count back - Planning

In the Year 1 Autumn curriculum, Week 4 is dedicated to reinforcing addition and subtraction within 10, with a particular focus on the skill of counting back to subtract. The lesson utilises a range of resources including differentiated worksheets, teaching slides, number lines, counters, and whiteboard pens. Key vocabulary such as 'add', 'subtract', 'number bonds', 'counting on', 'missing parts', 'part-whole', 'value', and 'number sentence' are introduced, with vocabulary cards and definitions available for further support. The lesson begins with a recap of number bonds to 10, using visual aids like part-whole models to help students identify missing numbers and encouraging memorisation of these fundamental combinations.

During the class, children engage in several activities designed to solidify their understanding of subtraction by counting back. They use number lines and counters to visualise the process, learning to start with the initial number in their head and not to include it when counting back steps. This approach helps address common misconceptions and reinforces the correct subtraction method. The lesson also includes partner work to foster discussion and reasoning, problem-solving tasks that require students to analyse and write number sentences, and a game to practice subtraction skills. To conclude, a 'Give me five' reflection exercise encourages students to think about what they've learned, the skills they used, and what they found challenging, ensuring they remember the key points of the lesson. Differentiated activity sheets cater to varying levels of ability, from 'Working Towards' to 'Greater Depth', providing appropriate challenges for each student.
