Percentages - Fractions to percentages - Presentation

In the second lesson of a series on percentages, students are taught the skill of converting fractions to percentages. The lesson begins with a discussion that revisits the meaning of 'percent' and how this understanding is crucial when converting tenths to hundredths. This foundational knowledge is essential as students embark on a series of activities designed to reinforce their ability to translate fractions into percentages. The lesson engages students with visual aids such as hundred squares, which provide a clear representation of the fractions that need to be converted. For example, students are shown how a fraction like 20/100 corresponds to 20%, making the concept of percentages more tangible and relatable.

Further activities challenge students to convert various common fractions into percentages. They complete tables where they match fractions such as 1/2, 1/4, 1/10, and 1/5 with their equivalent percentages: 50%, 25%, 10%, and 20%, respectively. This exercise helps them understand the process of converting different fractions by scaling them to a denominator of 100. Additionally, reasoning tasks are incorporated to deepen understanding, such as comparing the percentage of questions two students answered correctly in a Maths test. For instance, the lesson demonstrates that 4/5 is equivalent to 80%, which is more than 78%. The lesson concludes with independent work where students apply their knowledge to solve problems, ensuring they grasp the concept of converting fractions to percentages and can articulate their reasoning behind the solutions.
