Addition and subtraction within 10 - Fact families 8 facts - Planning

In an engaging Year 1 mathematics lesson, children are introduced to the concept of 'fact families' and the eight facts associated with them. The lesson forms part of the Autumn term's focus on addition and subtraction within 10 and aims to help pupils understand the relationship between these operations. Key vocabulary such as 'add', 'subtract', 'number bonds', and 'partitioning' is central to the lesson, and resources like differentiated worksheets, part-whole models, and various manipulatives like cubes and counters are provided to support learning. The lesson begins with a reminder of number bonds to 10, encouraging children to use their fingers to find pairs of numbers that sum up to 10, and progresses with activities that link addition and subtraction facts through both concrete and pictorial representations.

During the lesson, children work in pairs to discuss and write down the eight related addition and subtraction facts, using part-whole models to aid their understanding. They start by using given examples and then move on to creating their own sets of numbers to explore these relationships further. The plenary includes reasoning and problem-solving tasks where children identify parts and wholes in number sentences and explain any errors they find. Differentiated activities cater to varying levels of understanding, with more support provided for those 'Working Towards' and greater independence expected from those at 'Greater Depth'. By the end of the lesson, children are expected to confidently articulate and remember the eight facts of a fact family, having developed skills in partitioning and using the resources provided to enhance their learning.
