Addition and Subtraction - Subtract two 4-digit numbers (one exchange) - Worksheet

In the worksheet designed for mastering subtraction of two 4-digit numbers with one exchange, students are tasked with using place value charts and counters to visually represent and solve subtraction problems. This hands-on approach helps them grasp the concept of exchanging when there aren't enough units in a given place value to perform the subtraction. The worksheet guides students through several exercises where they must perform subtractions using the formal written method, while simultaneously using place value counters to aid their understanding of the exchange process.

The exercises include a variety of subtraction problems, where students are required to find the differences between two 4-digit numbers. For instance, when subtracting 7 from 5 in the units' place, students learn to exchange one ten for ten ones, thereby making the calculation possible. The worksheet emphasises the importance of explaining why an exchange has taken place, reinforcing the concept and ensuring a deeper understanding. Students also tackle problems where they must determine the missing numbers in a subtraction calculation, further challenging their comprehension of the topic. The goal is to develop fluency and precision in subtracting large numbers, with a clear understanding of the exchange process.
