Decimals and Percentages - Percentages as Fractions and Decimals - Starter

In a set of exercises designed to enhance Year 5 students' understanding of decimals and percentages, the tasks are varied and practical. One activity, 'Fluent in Four - Revision', challenges students with quick-fire arithmetic questions, such as division and multiplication involving decimals. For instance, students are asked to divide 63 by 7 and to calculate the result of doubling 242 divided by half of 22. These questions aim to consolidate their numerical fluency and revise key mathematical concepts.

Another part of the lesson involves geometric reasoning where students must identify different types of triangles – isosceles, scalene, or equilateral – based on their side lengths. Additionally, real-life scenarios are used to apply their knowledge of percentages and decimals. Students are presented with cinema ticket prices for adults and children on both weekdays and weekends, and they must calculate the total cost for a family's cinema visit on these days. Furthermore, they engage with a problem that involves a hundred square where certain percentages are shaded in different colours. Students must determine what percentage of the square is not shaded by subtracting the given percentages of yellow and purple from the whole. These exercises not only test their mathematical skills but also encourage the practical application of percentages in everyday situations.
