The lesson has gone fairly well so far. I have used it with all three proficiency levels with my boys and girls' 1st grade HS students. I did end up adding a file that I borrowed (and modified) from ESL Printables... It's a cell phone template (2 blank phones per page, so I could print, cut, and give half sheets). The students did a little more coloring and decorating than actual writing in some classes, but it still was well-received.
The problem is, even my higher level students still didn't get very far with actually reading their text messages to the class since we frequently ran out of time. I didn't manage the time as well as I wanted to since I had to take a little longer explaining some of the abbreviations in the PPT. What surprised me were the blank looks when I asked the students if they liked text messaging (I reworded it SMS and they still stared). I found that by telling the students (especially the boys) that these were useful terms for online gaming, they got a lot more interested.
The presentation and practice went well, but for production they mainly accomplished written instead of spoken production. Still, I'm glad for the materials and they helped me out a lot this week! Sometimes my co-teachers are rather inactive in class, but for this unit, they got caught up in the spirit of things and helped give hints and translation to the students to speed up the pace a little. Almost none of my students knew "LOL"! Wow... Thanks for the lesson idea!
