In the Year 5 Spring term curriculum, students delve into the intricacies of fractions, specifically focusing on subtracting mixed numbers through the technique of flexible partitioning. The National Curriculum objectives set the stage for learners to add and subtract fractions with the same denominator or denominators that are multiples of the same number, and to multiply proper fractions and mixed numbers by whole numbers with the support of visual aids. Key vocabulary such as 'flexible partitioning', 'fraction', 'mixed number', and 'equivalent fraction' are introduced to equip students with the necessary language to navigate the unit. The lesson plan includes a variety of resources, including worksheets and a presentation, to facilitate learning.

The lesson begins with a recap of previous knowledge on fractions, leading to activities where students practice subtracting fractions with mixed numbers. They are taught to use flexible partitioning to break down wholes into more manageable parts, enabling them to perform the subtraction. For example, students learn how to convert a whole into an equivalent fraction to facilitate subtraction when the fractional part of the mixed number is smaller than the fraction being subtracted. The lesson progresses through guided activities, partner discussions, and independent work, culminating in group work where students apply reasoning to solve problems and discuss different partitioning strategies. The lesson aims to clarify common misconceptions and reinforce understanding through a 'Give me five' reflective exercise, where students consider what they have learned, the skills they have used, and any challenges they faced, ensuring they remember the key concepts of the lesson.
