Addition and Subtraction - PowerPoint

The Addition and Subtraction PowerPoint aims to enhance Year 6 students' proficiency in number operations, including addition, subtraction, multiplication, and division. The lesson's objectives focus on solving multi-step problems in various contexts, requiring students to decide on the most appropriate operations and methods. To consolidate their knowledge, students engage in discussions with their partners about different strategies for addition and subtraction, such as mental methods, number lines, concrete or pictorial representations, formal written methods like the column method, rounding and adjustment, and expanded column addition. These discussions are aimed at reinforcing their understanding and encouraging them to think critically about the best approach for different types of calculations.

The teaching resources include activities that challenge students to apply their knowledge in practical scenarios. For instance, they are tasked with determining the most effective method to solve given calculations, whether mental or written, and explaining their choices. The lesson also provides top tips to ensure accuracy, such as copying numbers correctly, placing digits in the correct value columns, paying attention to the operation used, exchanging or carrying tens when necessary, and checking answers using inverse operations. Students are encouraged to work through calculations, reflect on the strategies they use, and complete worksheets that require careful consideration of place value. The resources cater to different learning stages, from fluency to reasoning and problem-solving skills, ensuring a comprehensive understanding of addition and subtraction.
