Fractions - Subtract from whole amounts (Bar Models) - Planning

In this interactive lesson tailored for Year 4 students during their Spring term on fractions, the focus is on learning to subtract fractions from whole numbers using bar models. The session starts with a brief recap of previous knowledge on subtracting fractions, but this time with an emphasis on whole amounts. Students are shown complete bar models and taught how to visually represent the subtraction of fractions by crossing out parts of the bar. This method helps to solidify their understanding of the concept in a tangible way. The lesson employs a variety of resources such as worksheets, presentations, cubes, and strips of paper, and encourages the use of key vocabulary including terms like numerator, denominator, and bar model.

During the lesson, students engage in hands-on activities where they use physical objects or draw bar models to practice subtracting fractions. They are prompted to discuss with their peers about the similarities and differences they observe in their models. The independent learning segment involves completing differentiated worksheets to reinforce the concepts taught. The lesson aims to address common misconceptions, such as the correct way to 'cross out' the numerator from the subtrahend. As the lesson concludes, students reflect on their learning, discussing what they've understood and the skills they've found challenging. They also consider the strategies and tools that aided their learning. The lesson caters to different levels of mastery, from working towards expected standards to greater depth, with tasks ranging from using visual aids to solve subtraction problems to tackling multi-step questions involving fraction subtraction.
