Decimals - Add Decimals with Different Decimal Places - Starter

In a series of mathematical challenges designed for Year 5 students, the focus is on enhancing fluency in arithmetic and problem-solving skills. The 'Fluent in Four' revision segment starts with a multiplication task where students calculate 9 times 7. The problems are set within real-life contexts, such as calculating the total number of novels on bookshelves. In this particular problem, students are asked to determine how many of the 48 books, spread equally across 3 shelves, are novels, given that 3/8 of them are. Another task involves comparing the masses of two suitcases, where students must find the total mass when one suitcase is 2.3kg lighter than the other, which weighs 4.7kg.

Additionally, students are presented with a scenario involving a plane's altitude. They must calculate the new height of the plane after it descends first by 7,557 feet and then by a further 218 feet from an initial altitude of 26,395 feet. These problems are designed to test and improve the students' ability to work with decimals and understand the concept of subtraction in practical situations. The exercises are aimed at reinforcing their knowledge and application of basic mathematical operations, including multiplication, division, and the handling of decimal numbers in various contexts.
