Four in Four Subtraction Set I - 6d - 5d 2 exchanges

The "Four in Four Subtraction Set I" is a series of timed worksheets designed to challenge Year 5 students with subtraction problems that require two exchanges. Each worksheet contains four subtraction calculations, where students must subtract a five-digit number from a six-digit number. The aim is for students to complete all four calculations within four minutes, testing both their arithmetic skills and their ability to work under time pressure. The subtraction sets are structured to progressively build the students' competence and confidence in handling larger numbers and more complex exchanges.

The worksheets are neatly organized into sets, each set comprising of multiple sheets with four problems each. For example, the first sheet in a set might present problems like "336190 - 14298" and "255192 - 24397," while another sheet offers challenges such as "869293 - 29397" and "983981 - 54867." To assist both students and educators, the answer keys are provided, offering solutions like "513081 - 12172 = 500,909" and "424858 - 16059 = 408,799." These resources are created to support the development of numerical fluency and are a testament to the thoughtful educational materials provided by KS2Gems in 2020.
