Ratio - Ratio and Fractions - Presentation

In a comprehensive set of teaching slides focused on the interplay between ratio and fractions, students are invited to delve into the mathematical concepts that connect these two areas. The lesson begins with a review of fundamental fraction knowledge, prompting students to recall what the denominator and numerator represent. This foundational understanding is crucial as they embark on discovering how ratios relate to fractions. The lesson includes a variety of activities designed to solidify this connection. For instance, one activity presents a scenario where the ratio of carrots to radishes is given as 2:5, and students are tasked with determining the corresponding fractions for each vegetable.

A subsequent activity employs a bar model to visually demonstrate a ratio of 1:3:4, challenging students to deduce the denominator of the fractions and to express each section of the model as a fraction of the whole. Another engaging activity confronts students with a basket of green and purple vegetables, where they must figure out the ratio of purple to green vegetables, given that two-thirds of the basket's contents are green. The lesson also includes reasoning exercises, such as evaluating statements about the ratio of different types of trees planted in a garden and determining the truth of statements regarding the ratio of black and yellow marbles in a bag. These exercises are designed to encourage critical thinking and to deepen students' comprehension of how ratios and fractions are intertwined in various contexts.
