Four in Four - Subtraction Set C - 4d - 3d with exchanges

The "Four in Four" exercise by KS2Gems is a fast-paced mathematical challenge designed for Year 4 students to practice their subtraction skills. Specifically, this task, Set C, involves subtracting a three-digit number from a four-digit number with the added complexity of exchanges. Each worksheet presents four different subtraction calculations that students are encouraged to complete within a tight timeframe of four minutes. This exercise not only tests their numerical proficiency but also their ability to work accurately under time pressure. The sheets are clearly labeled, with space provided for students to write down the date and their name before tackling the problems.

With ten different sheets available in Set C, there's ample opportunity for repeated practice, which is crucial for mastery of the skill. Each sheet contains a unique set of calculations, ensuring a broad range of examples. The corresponding answer key provides a quick reference for educators to check students' work. For instance, on Sheet 1, the subtraction problems range from 6504 - 276 to 5643 - 738, with answers such as 6228 and 4905, respectively. These exercises are designed to reinforce students' understanding of subtraction across a variety of numerical combinations and to develop their confidence in handling exchanges, a vital step in their mathematical development.
