Four in Four Addition Set F - 5d + 5d + 4d

The "Four in Four Addition Set F" is a series of arithmetic exercises designed to challenge Year 5 students with the task of adding together three numbers, each of varying digit lengths, within a four-minute time frame. This collection of worksheets, created by KS2Gems in 2020, is structured to progressively build students' speed and accuracy in performing addition calculations. Each sheet presents a set of four calculations that combine a five-digit number, another five-digit number, and a four-digit number. The aim is for students to complete all four calculations in under four minutes, fostering a quick and confident approach to addition.

The worksheets are organised into ten sheets, each containing different number sets for the students to add. For example, one set of numbers on Sheet 1 might include 36,004 + 14,298 + 2,916. In addition to the practice sheets, KS2Gems provides an answer key for each sheet, allowing for quick correction and feedback. The answer key lists the correct sum for each set of numbers, such as the sum of 11,265 + 12,172 + 1,257 equalling 24,694. This structured practice is not only meant to enhance computational skills but also to instil a deeper understanding of number sense and place value in the context of addition.
