Test your students' ability to spot mistakes and develop their understanding with this activity. Pupils are given two different answers to a question and have to determine which is correct (tick) and which is wrong (trash). They then have to explain what misconception has led to the incorrect answer.
This resource includes increasingly difficult questions on rationalizing the denominator. Questions start with rationalizing the denominator where the denominator is its lowest, to denominators that can be simplified. Later questions involve rationalizing the denominators by using the conjugate pair. Full instructions, ideas extension, and a solution are provided in the resource - what more could you need?
