Addition and Subtraction - Add two 4-digit numbers – more than one exchange - Starter

In this Year 5 maths lesson focusing on addition and subtraction, students are challenged with adding two 4-digit numbers that require more than one exchange. The lesson starts with a "Fluent in Four" revision exercise where learners practice their skills by performing calculations such as subtracting 3,874 from a number represented by 6 thousands, 5 hundreds, and 7 ones. They also work on adding place value counters together to solve problems like 9,058 minus 4,781, reinforcing their understanding of the place value system.

The lesson continues with exercises that help students visualise and calculate the exchange process when adding numbers like 5,345 and 722 or 8,088 and 233. They use bar models to subtract fractions and find differences between numbers, such as comparing 47 hundreds, 19 tens, and 5 ones to 16 hundreds and 43 tens. Through these activities, students learn to write calculations in numbers, showing where and why exchanges are necessary. This deepens their comprehension of complex addition and subtraction, setting a solid foundation for more advanced arithmetic operations.
