Addition and Subtraction - Adding four digit numbers (one exchange) - Worksheet

The worksheet from Master the Curriculum focuses on enhancing fluency and precision in adding four-digit numbers, with particular emphasis on exercises that involve one exchange. Students are tasked with using place value counters to visually represent numbers and then perform column addition to solve the problems. For example, they are presented with scenarios where they need to calculate the total cost of purchases, such as Tia buying a phone and a laptop, or a shop depositing cash into a bank. The worksheet provides a practical application of addition, asking students to cut out cards, add the place value counters together, and write the calculations in number form, clearly showing any exchanges that occur. The purpose of the exchange is explained to help students understand the regrouping process in addition.

The worksheet includes a variety of real-life scenarios to apply the mathematical concepts. For instance, students calculate the combined cost of gadgets bought by Tia and her friend Esin, or the total expenses for Zach's family holiday including insurance and flight upgrades. The worksheet guides students through these calculations step by step, reinforcing the concept of exchanging when the sum of one column exceeds nine. This hands-on approach to learning not only aids in mastering the technique of column addition but also helps students grasp the practical use of mathematics in everyday financial decisions. The worksheet concludes with a section of answers, allowing students to check their work and ensuring they have correctly understood the process of adding four-digit numbers with exchanges.
