Four in Four - Addition Set E - numbers with 1 and 3 decimal places

The 'Four in Four' exercise is a fast-paced addition challenge tailored for Year 6 students, aiming to enhance their arithmetic skills, particularly in adding numbers with one and three decimal places. Each worksheet presents four addition problems, and students are tasked with completing these calculations within a tight timeframe of four minutes. The exercise is designed to encourage accuracy and speed in dealing with decimal numbers, a fundamental aspect of the maths curriculum. For example, one worksheet might require students to sum 60.441 and 29.3, or 85.7 and 49.976, testing their ability to align decimal points and correctly perform the addition operation.

The worksheets are systematically organized into sets, each containing a distinct collection of addition problems. The numbers involved vary in complexity, with some problems having one decimal place while others have three, requiring careful attention to detail. This exercise not only supports the development of numerical fluency but also prepares students for more complex mathematical concepts. To aid in the learning process, an answer key is provided, allowing both students and educators to verify the accuracy of the completed work. For instance, the correct answer for the addition of 26.555 and 12.9 is 39.455, and for 85.7 plus 49.976, the solution is 135.676. These answer sheets serve as a valuable resource for immediate feedback and self-assessment.
