Four in Four Subtraction Set E - 5d - 4d 1 exchange

The "Four in Four Subtraction Set E" is a series of timed math challenges for Year 5 students, designed to test and improve their subtraction skills. The task involves completing four written subtraction calculations in four minutes. Each worksheet presents a set of problems where a five-digit number is subtracted by a four-digit number, requiring one exchange to solve. For instance, students might be given a problem such as subtracting 4,298 from 36,390. This exercise not only helps students practice their subtraction but also enhances their ability to work accurately under time constraints.

The worksheets are organised into sets, each containing different subtraction problems to solve. These problems are crafted to incrementally challenge the students, with the requirement of performing an exchange adding an additional layer of complexity. After the students complete the calculations, they can check their answers against the provided answer key. For example, the correct answer for the problem 36,390 minus 4,298 is 32,092. This exercise is a valuable tool for reinforcing mathematical concepts and developing quick, efficient calculation skills in young learners.
