Addition and subtraction within 20 - Add ones using number bonds - Planning

The lesson plan for Year 1 students in the Spring term focuses on enhancing addition and subtraction skills within 20 by using number bonds. The session starts with a small step starter to recap previous learning, followed by a class teaching input that introduces the key concept of adding ones using number bonds. To support this learning, differentiated worksheets and teaching slides are provided, along with practical resources such as ten frames and two-colour counters. The key vocabulary for the lesson includes 'addition', 'number bonds', and 'commutative', with further resources available for these terms.

The lesson's activities are designed to help children visualise the relationship between numbers and their components. In the first activity, students use pictorial images to understand how a number like 12 is composed of 1 ten and 2 ones, and then learn to add more ones to it. For instance, adding 4 ones to 2 ones makes 6 ones, resulting in the number 16 when combined with the original ten. The second activity employs a part-whole model to further illustrate the concept of adding ones to a ten. This activity also introduces the commutative property of addition, showing that numbers can be swapped in an addition sentence and still yield the same result. After the guided learning, children work independently on differentiated worksheets tailored to their level of understanding, from working towards the expected level to achieving greater depth. The lesson concludes with a reflective 'Give me five' plenary, where children consider what they've learned, the skills they've used and found challenging, and the resources that have supported their learning.
