Addition and subtraction within 20 - Add by counting on - Planning

In the first week of Spring term, Year 1 students focus on addition and subtraction within 20, with a particular emphasis on mastering the skill of 'add by counting on'. The National Curriculum objectives for this unit include understanding number bonds within 20, interpreting mathematical statements with addition, subtraction, and equals signs, and solving problems using concrete and pictorial aids. Key vocabulary such as 'addition', 'commutativity', 'represent', and 'counting on' are introduced, providing a foundation for the students' learning. A variety of resources, including differentiated worksheets and teaching slides, are used to facilitate learning, along with practical tools like ten frames and coloured counters.

The lesson begins with a recap of previous learning, followed by activities where students practice the technique of adding by counting on from a given number instead of starting from one. They are encouraged to understand that numbers increase in value when added. Practical activities involve using domino examples and digit cards to help children visualise the counting process. The lesson structure allows children to explore different ways of forming addition sentences and to recognise that starting with the larger number is more efficient. To assess understanding, a 'Give me five' reflection activity prompts students to consider what they've learned, the skills they've used, and any challenges they faced. The lesson caters to varying levels of ability, with support such as number tracks for those working towards the expected level, and more challenging tasks for those ready for greater depth.
