If you want to be a really effective teacher, get a laser pointer! They cause only a dollar or two at most and really help a teacher effectively modify curriculum.
With a laser pointer, you can be helping a student and very quickly point to what you are talking about: spelling, a picture, a thing and facilitate student understanding. Like other forms of modification – using pictures, underlining key vocabulary, dictionaries, highlighters, a laser pointer effectively helps students understand and learn.
If you really want to get spiffy, get a pointer that also works with power point. Then you can move around the classroom while controlling the presentation. Students at the back of the class will love you!Get a Laser Pointer!,
