Fractions - Add and Subtract Fractions (1) - Planning

This Year 6 mathematics lesson plan focuses on adding and subtracting fractions within the unit fraction (fractions less than one) where the denominators are related by multiples. The key objective is for students to understand the importance of finding the lowest common multiple (LCM) to determine a common denominator. The lesson starts with a recap of prior knowledge and presents a series of activities. In the first activity, students engage in Partner Talk to discuss why it is incorrect to add or subtract both the numerator and denominator directly, and instead, how to find the LCM to align the denominators. This is followed by hands-on practice where children apply this method to various examples.

As the lesson progresses, the children work through more complex tasks, such as comparing the size of fractions before and after finding a common denominator and solving word problems that require the application of the previous day's learning. Group work encourages discussion and the identification of any misconceptions, particularly around the significance of the LCM in establishing common denominators. The lesson also includes a plenary where students reflect on their learning, discussing what they found challenging and what strategies helped them. Differentiated worksheets for independent learning cater to varying levels of understanding, from working towards the expected level to achieving greater depth in adding and subtracting fractions.
