Four in Four - Addition Set A - numbers with 1 decimal place

The "Four in Four" exercise is a series of timed addition worksheets designed to challenge Year 6 students' ability to perform calculations with numbers that have one decimal place. Each sheet contains four addition problems, and the goal is for students to complete all four calculations within a four-minute timeframe. This activity aims to enhance the students' speed and accuracy in solving addition problems. The worksheets are part of the "Y6 ADDITION: SET A" series and are numbered from Sheet 1 to Sheet 10, each presenting a unique set of numerical challenges.

The worksheets are structured to progressively increase in difficulty, starting with simpler sums on Sheet 1, such as "60.4 + 29.3" and "85.7 + 49.9", and advancing to more complex calculations on Sheet 10, for example, "21918.7 + 5153.9" and "407762.9 + 24532.9". This progression is designed to build the students' confidence and proficiency with addition. The answer key provided for each sheet allows for quick verification of the students' work, ensuring that they can receive immediate feedback on their performance. These worksheets are a valuable resource for teachers to assess and reinforce their pupils' arithmetic skills, particularly in preparation for more advanced mathematical concepts.
