I am a returning first year teacher working in the Caribbean, on one of the smallest island nations, Grenada. I teach both Math and Science at the high school level and would love to introduce technology into my classes. I, like other high school teachers in my country, do not have my own room and must go from class to class. I therefore need a lightweight option to using multimedia. I think a mini projector will be useful but I would also like to know what else I can use. One thing is for sure, since this is coming out of my own pocket, "cringes", I need a VERY affordable plan. Any advice, anyone?
