Fractions - Recognise a third - Presentation

In today's lesson, Year 5 students will delve into the concept of fractions, specifically focusing on recognising and understanding a third. The term 'third' refers to one of three equal parts of a whole, and this lesson aims to familiarise students with this fraction. Through engaging teaching slides, students will explore the meaning of 'third' in various contexts and discuss where they have previously encountered this term. The lesson will highlight the basic principles of fractions, including the roles of the numerator and denominator. The numerator, displayed as the top number of a fraction, indicates the number of parts being considered, while the denominator, the bottom number, denotes the total number of equal parts into which the whole is divided.

To reinforce these concepts, students will participate in a series of activities. The first activity involves a pizza divided into equal parts, where students will identify each part as a third and complete related sentences. Subsequent activities challenge students to shade one third of different shapes, compare and contrast the shaded areas, and determine which shapes represent one third. The lesson also includes reasoning tasks, such as evaluating a statement by Leanna about the portion of pizza she has and determining the length of cloth pieces based on the fraction shown. Finally, independent work encourages students to identify thirds in various shapes, divide a pizza into thirds, and complete given sentences, providing a comprehensive understanding of what it means to recognise a third.
