Four in Four - Addition Set D - numbers with 3 decimal places

The 'Four in Four' challenge is an engaging math activity designed to enhance the addition skills of Year 6 students. It consists of a series of worksheets, each containing four addition problems that involve numbers with three decimal places. The task is to accurately complete all four calculations within a tight four-minute timeframe, encouraging both speed and precision in arithmetic. This exercise not only reinforces the concept of decimal place values but also promotes quick mental computation and written calculation proficiency among pupils.

Each worksheet presents a different set of addition problems, progressively increasing in complexity. For example, Sheet 1 includes sums like 60.444 + 29.317 and 85.076 + 49.974, while Sheet 10 presents more challenging calculations such as 21918.307 + 5153.954 and 407762.009 + 24532.099. The answers are provided separately, allowing both students and educators to check the accuracy of the completed work. This structured practice is an excellent way for children to build confidence in handling numbers with decimal points and to develop their numerical fluency.
