Dear Erin,
I just wanted to address your feedback re the clickers for the Preterite vs. Imperfect powerpoint. While I do use this powerpoint with Clickers, many people use whiteboards and students hold up their answers. I mentioned the clickers bc some schools own sets that can be used with the powerpoint, but they really aren't necessary to run the lesson.
As for irregulars and verb endings, this powerpoint was designed to address the decision making process between the two past tenses, assuming students had already learned to make both tenses of verbs independently and had been using them for some time. I am sorry if you felt the product was misleading. Sincerely, Barbara Davis
