Addition and Subtraction - Adding four digit numbers (no exchange) - Planning

In a Year 4 mathematics lesson focusing on Addition and Subtraction, students are introduced to adding four-digit numbers without the need for exchanging. The lesson utilises a variety of resources, including place value counters and grids, to support the learning process. Children begin by recapping previous learning before diving into the new concept. They are encouraged to use practical, abstract, and mental methods to understand how to add two four-digit numbers together. Key vocabulary such as 'total', 'ones', 'tens', 'hundreds', 'thousands', and 'column' is emphasised, and students can access vocabulary cards and definitions to aid their comprehension.

The lesson structure includes a starter activity where students attempt a calculation independently, allowing the teacher to observe the various methods used. Practical activities involve creating four-digit numbers with counters and writing the calculations using the column method, with particular attention to place value. Partner and group work help reinforce the learning, with activities designed to transition students from place value grids to written columns. As the lesson progresses, children tackle missing number questions, applying their knowledge of column addition to solve problems. The lesson aims to clarify common misconceptions such as place value understanding and aligning columns correctly. Differentiated worksheets cater to varying levels of proficiency, from working towards expected standards to achieving greater depth in addition skills.
