I use the WEIRDO chart when I first introduce the subjunctive. I tell my students that this chart will become very handy for the rest of their Spanish years. When I introduce the subjunctive I always tell my students that their lives are about to change. They keep because they know they will have to refer to it often.
This is the color version of the chart I use when teaching the subjunctive. Students prefer the color columns and use the phrases more often this way. ¡Gracias!
