The Quadratic Formula - spot the mistake
A short activity to ensure the class are typing the correct things into their calculator.\n\nThe PowerPoint starts with a few model examples and then gives questions where mistakes have been made - wrong signs and brackets in the wrong place.\n\nClick the circle to find the error and then press right on keyboard to reveal solution.\n\nThe final slide is correct - deliberately as they should be checking answers which are correct in the first place.
