Addition and Subtraction - Adding whole numbers with more than 4-digits - Worksheet

Students in Year 5 are presented with a comprehensive lesson on adding whole numbers with more than four digits, utilizing formal written methods of addition and subtraction. The lesson focuses on enhancing their fluency and precision in mathematical calculations. To facilitate learning, differentiated worksheets and teaching slides are provided, allowing for varying levels of difficulty. Key vocabulary such as 'column addition', 'addition', 'subtraction', 'exchange', and 'calculation' is introduced to reinforce understanding of the concepts involved.

The lesson's activities encourage students to apply their knowledge of place value to align numbers correctly for column addition. They are also introduced to problem-solving techniques using manipulatives and pictorial representations for visual support. The tasks include cutting out word problems and solving them by writing out the calculations. Key questions prompt students to think critically about the process of exchanging numbers in different columns and the implications of adding numbers with differing digit lengths. As they progress, students tackle calculations that require one, two, or more exchanges, catering to different learning stages from 'Working Towards' to 'Greater Depth'. To further develop reasoning and problem-solving skills, students engage with Gattegno charts, challenging them to explore numerical relationships and transformations.
