Fractions - Subtract Mixed Numbers - Planning

In the Year 5 curriculum, the lesson plan for Week 4 of the Spring term is dedicated to teaching students how to subtract mixed numbers. The lesson begins with a review of previous learning and a 'fluent in four' questions starter to get the children ready for the day's lesson. The key vocabulary for the lesson includes terms such as 'fraction', 'mixed number', 'subtract', 'numerator', 'denominator', and 'equivalent fraction'. Two main models are used for visualising the subtraction process: the table model and the bar model. The initial activity focuses on using the table model to subtract fractions from mixed numbers without breaking through a whole number. For students who are more confident, the lesson introduces more complex calculations as a challenge, preparing them for the following week's lessons.

The lesson continues with Activity 3, where students solve a series of calculations using either the table model or bar modelling, sharing their answers and methodologies with the class. Group work involves reasoning tasks from teaching slides, encouraging collaboration and discussion. The plenary session addresses any misconceptions and reinforces the lesson's key concepts. Students reflect on what they have learned, the skills they have used, and what they found challenging. Differentiated worksheets support independent learning, catering to varying levels of proficiency, from working towards expected standards to achieving greater depth. The lesson aims to ensure that students can apply their knowledge of equivalent fractions to find common denominators and subtract across numerators, enhancing their understanding of subtracting mixed numbers.
