This is a powerpoint with 18 slides. Each slide has a picture and a sentence. The teacher should distribute popsicle sticks with "ser" written on one, and "estar" written on another. Or, you can use whatever you want to have the kids hold up either SER or ESTAR for each slide shown. An example of a slide: A sentence that says "The boy is sick today." There is also a picture of a sick boy on the slide. Students would hold up either "SER" or "ESTAR" to indicate comprehension of this concept.
