Anne’s book is now out on the Teacher’s Discovery website, but at this point only in electronic form. The hard copy is very close to appearing there, however. You can get the ebook from them or from me at benslavic.com. Only TD will sell the hard copy when it appears later this fall.
WL teachers of any approach can and should in my opinion take these scripts for a spin. They fit well with a non-targeted approach because they were conceived of and written as ways to talk about certain common occurrences/regular “life stuff” without focusing on certain predetermined words originating in any kind of high frequency, thematic, backwards planned, list of any kind connected to a textbook.
