Addition and subtraction within 20 - Add by counting on 2 - Planning

In this Year 1 maths lesson, young learners are introduced to the concept of addition by counting on, with a focus on the commutative property of addition which teaches them that starting with the largest number makes the process more efficient. The lesson is structured with a starter, class teaching input, independent learning, and a plenary. Key vocabulary such as 'addition', 'commutativity', 'represent', 'largest', and 'counting on' is emphasised. Using ten frames and two-colour counters, children practice adding by counting on through storytelling and practical exercises. They are encouraged to understand that they are adding to an existing number rather than just combining two separate numbers. This is reinforced with number stories that follow the 'First, Then, Now' structure, helping children to visualise the addition process and write corresponding number sentences.

The lesson progresses with activities that encourage children to use ten frames to represent addition problems, highlighting the importance of completing one ten frame before starting another. This visual method aids in understanding the concept of counting on, especially when dealing with numbers that exceed ten. Differentiated worksheets cater to varying levels of ability, from those working towards understanding to those who are ready for greater depth. The lesson concludes with a reflective 'Give me five' activity, where children recap what they have learned, the skills they used, any challenges they faced, the resources that assisted them, and the key points they will remember. This structured approach ensures that pupils not only learn to count on for addition but also develop the ability to create and solve their own number stories, fostering a deeper comprehension of the addition process.
