Students have different learning styles, so I figured there was nothing to loose if I introduced these two acronyms into the "ser" and "estar" unit. Being somewhat successful, I decided to create these two videos to "flip" my lessons a little bit (see below). I hope they help you teach these two tricky verbs.
There are a few other videos on FluencyProf's YouTube Channel. Take a look when you get a chance.
Finally, please leave a comment below this blog entry to share your approach on teaching "Ser" and "estar". What has worked for you so far? Thank you for sharing your expertise!
