Thirty slides highlighting each a different Greek Root word. I have sentences that your students can use to type the correct word into.
I use these in correctional education, so there may be a little prison slang in here- you can modify that out by typing in your own appropriate sentences.
I use it by downloading it onto my student computer accounts and then i let them read the entire slide, study the root word and then type the correct words into the cloze sentences below.
When they are finished they save their work to continue.
This could also be printed as handouts 2 per page and used kind of like a worksheet.
