Fractions - Add and Subtract Fractions (1) - Worksheet

The "Add and Subtract Fractions (1)" worksheet is designed to enhance students' fluency and precision in dealing with fractions. The National Curriculum objective for this lesson is to enable students to add and subtract fractions with different denominations and mixed numbers by using the concept of equivalent fractions. To facilitate this, differentiated sheets and teaching slides are provided as resources. Students are encouraged to identify the lowest common multiple (LCM) to find a common denominator for the fractions in question. The vocabulary for the lesson includes terms such as 'fractions', 'numerator', 'denominator', 'multiples', and 'lowest common multiple'. By finding the LCM, students can confidently add and subtract fractions with the same denominator, using bar models to visualise the process.

Throughout the lesson, key questions guide students to understand the necessity of finding a common denominator when dealing with fractions that have different denominators. The worksheet activities progress from using given methods to find the LCM of denominators to completing all steps independently when adding and subtracting fractions. For reasoning and problem-solving, students tackle increasingly complex tasks, starting with simpler fractions with denominators that are multiples of 5 and moving on to more challenging scenarios. Students are required to apply their understanding of finding a common denominator through the LCM to solve reasoning questions that involve slightly trickier fractions, thus deepening their comprehension of the topic.
