I just happened across this (found here: http://iteachduallanguage.blogspot.com/2012/07/instead-of-i-dont-know.html ). I need to do something similar! I struggle with getting kids (ELL or not) to tell me when they didn’t understand what I just said. I love the idea of giving a script and making an anchor chart for it, along with some modeling/play acting lessons and so forth. This goes in my September plans!
