About This Lesson
3 lesson PowerPoints; does what it says on the tin. The tarsia makes a decent homework; easy to mark if you put a code on the middle of the tiles...something I shall do one day soon.With P7.2 PowerPoint any video that runs through the basics of waves is sufficient.
Two good quality PowerPoint. I have used the wave one in my lesson. The 5 questions on the last slide was a good wrap up.
