I have some familiarity with it (some of my HS teachers had one) and my mom has one in her classroom, too. She teaches a ½ combo, so I’m not sure if that’s going to be any help to you. I know that she shows videos and does vocab stuff on it, as well as playing computer games together (such as I Spy), but like I said…not too useful for 5th grade, eh? I guess it depends on how much prep work you want to do. Do you want more info?
