Simplifying fractions Spot the Mistake

The 'Spot the Mistake' activity is an engaging exercise designed for Year 6 students to deepen their understanding of simplifying fractions. In this activity, students are presented with a series of incorrectly simplified fractions and are tasked with three objectives: to identify the error made, to explain why it is incorrect, and to correctly simplify the fraction. This approach not only tests their knowledge of the subject but also promotes critical thinking and the use of mathematical language. The activity can be seamlessly integrated at the beginning or end of a lesson or used to address common errors observed in students' work.

Examples of the mistakes include simplifications such as reducing 8/12 to 4/16, 2/6 to 1/6, and 70/100 to 7/5. Each of these presents a unique learning opportunity where students must apply their knowledge of common factors and the rules of fraction simplification to spot and correct the mistake. For instance, they will learn that 8/12 should be simplified to 2/3, not 4/16, by dividing both the numerator and the denominator by their greatest common factor. By engaging in this exercise, students will not only practice simplification but also reinforce their understanding of equivalent fractions and the importance of accuracy in mathematics.
