Ratio - Calculating Ratio - Starter

In the 'Fluent in Four' revision segment of a Year 6 mathematics lesson, students are tasked with a series of calculations to sharpen their arithmetic skills. The exercises include a variety of problems, such as adding, subtracting, and finding fractions of numbers, all of which are designed to be completed quickly to build fluency. For instance, students might be presented with problems requiring them to work out the value of blank spaces in equations such as 31 over 96 or 7 over 12. This practice helps to consolidate their understanding of numerical operations and prepares them for more complex mathematical concepts.

The lesson continues with practical applications of mathematics, such as estimating and matching objects to their correct capacities, which are given in cubic centimetres. Students must use their judgement to associate the right volumes with different objects. Another activity involves converting between days and weeks, requiring students to complete a table that tests their understanding of time measurement. For example, they might convert 18 days into weeks and days or 90 days into the equivalent number of weeks and days. Additionally, the lesson covers the concept of ratio by dividing a total quantity into equal parts. Students learn that to find the value of one part of a total, such as 16 divided into 4 equal parts, they need to perform a division, in this case resulting in 4 for each part. These exercises are designed to deepen students' comprehension of ratios and proportions, as well as their ability to perform conversions and estimations.
