This is a Power point of common Latin and Greek roots. With the first click on each slide the root comes up. At that point students share and I write down as many words as they can think of that have that root. The second click a list of words come up that have that root and some have definitions. At this point students are trying to come up with what the root means. Finally, the last click of each slide is the root meaning and a picture that goes with the meaning. I have students record these in their notebooks to reference and study. There are 66 roots provided here.
