Four in Four - Subtraction Set E - 4d - 4d with exchange

The 'Four in Four' exercise by KS2Gems is a fast-paced and engaging activity designed for Year 4 students to sharpen their subtraction skills. The challenge is to accurately complete four calculations within a four-minute timeframe. Each calculation involves subtracting one four-digit number from another, and crucially, some of these require the student to understand and apply the concept of exchanging, also known as regrouping or borrowing. The subtraction sets, labelled as 'Set E', provide a sequence of worksheets, each containing a fresh set of four-digit minus four-digit problems to solve.

Worksheets are organized in a series, with each sheet presenting a new set of subtraction problems. The exercise not only tests the students' ability to perform basic arithmetic quickly but also reinforces their understanding of more complex subtraction where digits must be exchanged across place values. For instance, subtracting 3223 from 6504 or 2452 from 5643. To assist both students and educators, 'Four in Four' also offers an answer key that provides solutions to the subtraction problems from each sheet, ensuring that learners can check their work and educators can easily assess their students' progress and comprehension of the subtraction concepts taught.
