Four in Four - Subtraction Set B - 3d - 2d with exchange

The "Four in Four" subtraction worksheets, created by KS2Gems in 2020, are designed to challenge Year 3 students with a series of subtraction problems that require exchanging. Each worksheet, labeled as Set B, presents four calculations where students must subtract a two-digit number from a three-digit number. A key feature of these problems is that they necessitate borrowing from the next highest place value, a skill commonly referred to as 'exchanging' in British English. The goal for the students is to complete all four calculations within a four-minute time frame, testing both their arithmetic proficiency and their ability to work under time pressure.

These worksheets are organized into sets, with each set containing a variety of subtraction problems to be solved. For instance, Sheet 1 includes problems like 674 minus 56 and 543 minus 35, while Sheet 2 features calculations such as 682 minus 91 and 488 minus 19. The exercises get progressively more challenging, encouraging students to apply their knowledge and improve their speed and accuracy with each attempt. Additionally, the answer key is provided for each sheet, offering quick verification of the students' work and facilitating immediate feedback. Examples of the provided answers are 265 minus 38 equals 227 and 859 minus 69 equals 790, demonstrating the correct application of the subtraction with exchange method.
