About This Lesson
Multiplying and dividing surds together with short sets of questions to practice each rule. testple to show that (different) surds cannot be added. Test question to finish. Picture on title slide is "square roots" (worth asking the class what it is a picture of - if they like bad jokes!)
A nice lesson as an introduction to the basic rules of surds, the joke on the first slide is great! Some good consolidation questions are included on the powerpoint. The exam question at the end is a good extension but does require students to be confident with indices and multiplying together two brackets.
