Addition and subtraction within 10 - Fact families addition - Planning

In the second week of Autumn term for Year 1, students delve into the world of addition and subtraction within 10, focusing on the concept of fact families in addition. The National Curriculum objectives for this period include understanding number bonds and related subtraction facts within 10, interpreting mathematical statements with addition, subtraction, and equals signs, and solving one-step problems using various methods such as concrete objects and pictorial representations. Key vocabulary terms such as 'part', 'whole', 'addition', and 'fact family' are introduced, helping students to articulate their mathematical reasoning. The lesson encourages the use of part-whole models to visually represent number sentences, thereby enhancing the children's comprehension of how numbers can be partitioned and recombined in different ways to show the same total.

Differentiated worksheets and teaching slides aid the learning process, allowing children to engage with the material at varying levels of complexity. The lesson begins with a review of previous learning, where students explore the commutative property of addition through rearranging number sentences. As they progress, they are tasked with writing number sentences from given part-whole models and identifying missing numbers in equations. Interactive activities, such as writing addition fact families for images of coloured cubes, further reinforce the concept. The lesson addresses common misconceptions, particularly the placement of the equals sign in number sentences, and culminates with students reflecting on what they've learned, the skills they've used, and what they found challenging. This reflective practice ensures that students solidify their understanding of addition fact families and the relationship between parts and wholes in mathematical statements.
