Addition and Subtraction - Add two 4-digit numbers – one exchange - Worksheet

This worksheet from masterthecurriculum.co.uk is designed to help students enhance their fluency and precision in addition by tackling problems that involve adding two 4-digit numbers with one exchange. The worksheet provides a series of practical exercises that require learners to use column addition to combine place value counters and then write out the calculations numerically, clearly showing where exchanges are made. Students are asked to explain why exchanges are necessary, which deepens their understanding of place value and the addition process. Real-world scenarios, such as calculating the total cost of purchases or a shop's bank balance, make the exercises relatable and help students apply their mathematical skills to everyday situations.

The worksheet includes a variety of problems that challenge students to add together amounts such as the cost of a phone and a laptop or the total expenses for a holiday and insurance. In each case, they must demonstrate their ability to handle exchanges when the sum of the digits in a column exceeds nine. For example, when Tia buys a phone for £284 and a laptop for £2,151, students must calculate the total cost and show the exchange that occurs during the addition process. The worksheet not only reinforces the arithmetic skills but also encourages logical reasoning as students must articulate their understanding of the exchange mechanism in their calculations.
