Ratio - Using Ratio Language - Presentation

In a series of engaging lessons on ratio, students are introduced to the concept of using ratio language to describe relationships between quantities. The initial focus is on understanding what ratio means and where students might have encountered it before. The lesson progresses with activities that encourage students to complete sentences using ratio language in practical contexts. For example, they are asked to determine how many broccoli heads correspond to a given number of aubergines. This activity not only helps them grasp the concept of ratio but also applies it in a way that relates to real-life scenarios. The use of visual aids, such as cubes, further supports their learning by providing a tangible method to help complete the sentences and solidify their understanding of ratio.

Building on these foundational skills, the lessons continue with more complex reasoning tasks where students must apply their knowledge of ratios to solve problems. They are presented with situations such as Jude laying tiles in a pattern and are tasked with determining if she can continue the pattern without any tiles left over. This involves critical thinking as students must work out the ratio of blue to orange tiles and assess the quantities needed. Independent work challenges students to describe visual representations using "For every..." sentences and to verify the truthfulness of given statements about ratios. The lessons also encourage discussion on how ratios would change with different quantities, promoting a deeper comprehension of the concept and its dynamic nature in various situations.
