Four in Four Subtraction Set F - 5d - 4d with exchanges

The "Four in Four Subtraction Set F" is a series of timed mathematics worksheets designed for Year 5 students, focusing on the subtraction of five-digit numbers from four-digit numbers, which require exchanges. Each sheet contains four subtraction problems that students are challenged to complete within four minutes, testing their speed and accuracy in performing calculations. The exercises are intended to improve the students' fluency in subtraction by providing practice in borrowing from higher place values when the digits in the lower place values of the minuend are smaller than those in the subtrahend.

The subtraction sets are organized into ten sheets, each offering a unique set of problems that become progressively more challenging. The answer key provided for each sheet allows for quick checking of the completed calculations. For example, on sheet 1, the subtraction problem 36390 - 4898 results in an answer of 31492, demonstrating the exchange process. This educational resource, created by KS2Gems in 2020, is an effective tool for teachers to assess and enhance their pupils' subtraction skills in a fun and engaging manner, while also encouraging the development of mental arithmetic and problem-solving strategies.
