Four in Four - Subtraction Set I - numbers with 3 decimal places with exchanges

The "Four in Four" activity is a timed challenge designed for Year 6 students to practice their subtraction skills. Specifically, this set of exercises, named "Subtraction Set I," involves numbers with three decimal places where exchanges may be necessary. Each sheet presents four subtraction problems, and the goal for students is to complete all four calculations within a four-minute time limit. The task is not only a test of their arithmetic proficiency but also their ability to work accurately and efficiently under time pressure.

There are ten sheets in total, each with a unique set of subtraction problems. These exercises are intended to help students solidify their understanding of decimal subtraction and the concept of borrowing across decimal places. The activity sheets are clearly structured with space for the student to write their name and the date, alongside the subtraction problems. Answers are provided separately, allowing for easy marking or self-assessment. This educational resource was created by KS2Gems in 2020, aiming to enhance the mathematical skills of upper key stage 2 pupils.
