Addition and subtraction within 10 - Find the difference 2 - Planning

In the Year 1 Autumn term, students delve into addition and subtraction within 10, with a particular focus on finding the difference in Week 5. The lesson begins with a small step starter, where children recap previous learning and prepare to further explore the concept of finding the difference using bar models. The key vocabulary for this lesson includes terms such as 'bar model', 'addition', 'subtraction', 'fewer', and 'most', with resources available to support understanding of these terms. The class teaching input encourages children to recall the purpose of bar models and how they visually represent problems, aiding in the calculation of differences.

During the lesson, students engage in a series of activities designed to reinforce their understanding of comparison using bar models. Activity 1 demonstrates how to use a bar model to determine how many more pink gems there are than yellow ones. In Activity 2, children interpret a bar model to find out how many more or fewer books one child has compared to another. This leads to discussions around the concepts of 'fewer' and 'most'. The final activity introduces addition and subtraction number sentences, helping children relate these operations to the concept of finding the difference. Independent worksheet tasks allow children to apply what they've learned, while a plenary session, structured as a 'Give me five' reflective exercise, prompts them to consider what they've learned, the skills they've used, and any challenges they've encountered. Differentiated worksheets cater to varying levels of understanding, from working towards expected levels to achieving greater depth in the subject.
