Fractions - Add Mixed Numbers - Planning

In the Year 5 curriculum focusing on fractions, the fourth week of the spring term introduces pupils to the concept of adding mixed numbers. The lesson begins with a refresher of prior knowledge before moving onto the main task, which involves adding together mixed numbers that may include improper fractions. The class is taught to add the whole numbers and fractional parts separately, ensuring that the resulting mixed number is simplified to its simplest form. Key vocabulary such as 'proper fraction', 'improper fraction', 'numerator', 'denominator', and 'simplify' are emphasised, with resources such as worksheets and presentations aiding the learning process. Pupils engage in 'fluent in four' questions to test their understanding and are encouraged to discuss strategies for simplifying fractions that are part of their answer.

Different methods of adding mixed numbers are explored in the lesson, including converting mixed numbers into improper fractions to find a common denominator before adding and then simplifying the answer. Pupils practise these methods through a variety of activities, which are designed to reinforce their skills in partitioning numbers, finding equivalent fractions, and converting between mixed and improper fractions. Group work and independent activities provide opportunities for reasoning and problem-solving, with differentiated tasks catering to varying levels of ability. The lesson plan anticipates common misconceptions and addresses them through the teaching slides. Pupils are encouraged to reflect on the skills they used and what they found challenging, ensuring they remember the key concepts taught in the lesson. The learning journey is structured to guide pupils from working towards fluency to achieving greater depth in understanding and applying the methods of adding mixed numbers and improper fractions.
