Fractions - Find a half - Presentation

In the "Find a Half" lesson, part of a series on fractions for Year 5 students, the objective is to understand how to find one half of a set of objects. The lesson starts with a discussion prompt, asking students to consider how many equal parts a whole must be split into to find one half. This is followed by an activity where students share marbles between two containers equally and complete sentences to express the whole and the half. The lesson continues to reinforce the concept of halving through practical activities such as circling half the balloons and yoyos, and using counters to find half of given numbers, which helps to solidify the understanding of fractions in a visual and interactive manner.

As the lesson advances, reasoning tasks challenge students to apply their knowledge of fractions to different scenarios. One task asks students to determine if a peer correctly shaded half of a shape, while another prompts them to think of a number whose half falls within a specified range. These reasoning activities encourage critical thinking and a deeper comprehension of the concept of halving. Independent work further cements the learning, with exercises that involve finding one half of various objects and amounts, and reflective questions that ask students to consider the value of a whole and its half. The lesson aims to build a strong foundation in understanding and calculating halves, which is a fundamental skill in mathematics.
