Add and subtract decimal numbers that have the same number of decimal places [F10]

The task involves adding and subtracting decimal numbers with an equal number of decimal places, a key mathematical skill for students in Key Stage 2 (KS2). For example, a puppy's weight is recorded at 1.078kg, and if the puppy gains an additional 0.495kg, students are required to calculate the new weight by performing a simple addition. This exercise not only tests their ability to work with decimals but also helps to reinforce the importance of precision in calculations. Another challenge presents a sequence of numbers where students must determine the consistent increment and fill in the missing values, further honing their understanding of numerical patterns and sequences.

In a practical application of these skills, students are asked to calculate how much more money is needed for a sponsored walk target. With a goal of £450 and existing donations totalling £291.45, they must subtract the donations from the target to find the remaining amount required. This type of problem-solving is crucial for developing a real-world understanding of mathematics. The exercises are designed to be accessible yet challenging, ensuring that students at various levels of proficiency can engage with the content and improve their mathematical competence, particularly in dealing with decimals and understanding the relationships between numbers.
