Fractions - Recognise a third - Planning

In this Year 3 mathematics lesson, students are introduced to the concept of recognising a third. The lesson is structured to begin with a starter activity, followed by class teaching input, independent learning, and concluding with a plenary. The resources provided for this lesson include a teaching presentation, worksheets, counting objects like cubes, and mini whiteboards. Key vocabulary terms such as 'whole', 'part', 'equal', 'unequal', 'group', 'shape', 'number', 'half', 'quarter', 'more', 'less', and 'third' are emphasised to enhance understanding. Students are encouraged to use vocabulary cards and definitions available on the associated website to familiarise themselves with the terms.

During the class, children will explore the differences between a third, a half, and a quarter, both in terms of shapes and numbers. They will engage in a discussion to recall where they have encountered the term 'third' before, such as ordinal numbers or positions in a race. The teacher will explain fractions using visual aids, focusing on the numerator and denominator, and demonstrate how to divide a shape into three equal parts. Group activities involve shading one third of a shape, while practical work includes drawing and shading a third of a shape with a partner. Independent learning is facilitated through differentiated worksheets aimed at developing fluency and reasoning. Key questions guide students to a deeper understanding of thirds and the importance of equal parts. The lesson plan also outlines expectations for different levels of mastery, from working towards the expected level to achieving greater depth, with activities tailored to each student's understanding.
