Addition and subtraction within 20 - Find and make number bonds - Planning

In the Year 1 Spring term lesson on addition and subtraction within 20, the focus is on finding and making number bonds, a crucial step in understanding basic arithmetic. The lesson plan includes a range of resources such as differentiated worksheets, teaching slides, cubes, and a part-whole model to support learning. Key vocabulary terms like 'addition', 'number bonds', 'place value', 'related facts', 'fact family', and 'strategy' are integral to the lesson, with vocabulary cards and definitions available as supplementary materials. The lesson begins with a recap of number bonds to 10, setting the stage for exploring number bonds up to 20. Students are encouraged to work systematically and use their knowledge of number bonds to 10 to assist in finding those up to 20, highlighting the importance of place value in the process.

The lesson is structured to include partner work, where children engage in discussion and apply their understanding to record number sentences using counters and ten frames. Activities are designed to help children recognise patterns and relationships between numbers, with the instruction to move one cube at a time to find various number bonds. Reasoning and problem-solving tasks challenge students to represent number bonds on ten frames and correct mistakes, fostering deeper comprehension. The 'Give me five' plenary allows for self-assessment, where students reflect on what they've learnt, the skills they've used, and what they found challenging. The differentiated activities cater to varying levels of understanding, from 'Working Towards' to 'Greater Depth', ensuring all children can progress and solidify their grasp of number bonds within 20.
