In my school almost every classroom has a smart board. A smart board(if you don;t already know) is a board thats one big touch screen. A projector connected to the computer projects an image onto the screen. Then, the smartboard,also connected to the computer,is calibrated. You get 4 pens: Blue,Red,Green,and black plus an eraser. When they touch the screen they make a line. It is a big DS screen so you can go on the internet using the Smartboard screen
I want to get one.....but the problem is....they're $3,000. This is a very hi-tech thing they just starting using in my schools math and science classes.
