These are the notes I used for Ser and Estar. I always teach them together. I feel it is a lot less confusing for them to always know there are 2 verbs for am/is/are, and to always work to differentiate between them from the start. I teach them "Doctor Ser Helps Estar" to remember the acrostics, which I spelled out below. Also- I use the image of a Sharpie and Eraser to help them get a visual image of the 2 different verbs. I usually do a brainstorming activity where we talk about sharpies and erasers before I introduce the verbs.
