Ratio using relative quantity sizes worksheet

KS2Gems2022 presents a comprehensive worksheet to help children understand the concept of ratios through a variety of engaging activities. The first activity utilises interlocking cubes of different colours, where students are tasked with representing simple ratios such as 2:1, and then moving on to more complex ones. They can also observe pre-arranged cubes and deduce the ratios themselves. In the second activity, children are encouraged to use blank bar model templates and coloured crayons to visually represent ratios, again starting with simple ones and progressing to more intricate combinations. They also have the opportunity to interpret coloured bar models to state the corresponding ratios.

Moving on to the third activity, a Ratio Images PowerPoint is used to prompt students to write statements beginning with 'For every...' and to express the relationships they see as ratios. The fourth activity adds a practical and fun twist where children create mocktails using specific ratios, such as 1:2:3, and record their recipes with exact measurements, even naming their creations. Variations include altering the ratios, cup sizes, and the final volume of the mocktail. In the fifth activity, children face the challenge of determining missing measurements in preprepared mocktail recipes, requiring them to explain their methods. The sixth activity has students create and exchange their own ratio problems, solidifying their understanding through peer interaction. Finally, the seventh activity introduces real-life application by having students solve problems involving money, such as calculating the number of comics and bags of sweets that can be bought with a given budget, with variations to adjust the complexity of the task. The overarching objective of these activities is to solve problems involving the relative sizes of quantities using integer multiplication and division facts, fostering a deeper comprehension of ratios in practical contexts.
