so... what exactly is slamming
Obviously I'm not qualified to teach English, because I can't figure out what you mean by "slamming." Each student "slams" a card. You mean they turn the card over and use the word in a sentence, maybe? Wouldn't that get very easy and repetitive when the next students have had time to prepare a sentence for each word going down the line? Or is that the point, that they do get to be somewhat prepared when it's their turn to slam. I'm just going to improvise for today, but I'd definitely appreciate more details about how you're using this game.
