This is a two page worksheet that I use to first introduce the subjunctive to my students. The first page explain the meaning, why and how to use the subjunctive in spanish. There is also a chart with all the conjugations for the verb "hablar" as well as the blank spaces for students to do the conjugations for two other regular verbs like "comer" and "escribir".
The second page presents the subjunctive as a wedding. My students easily make connections with the two clauses when they see them as the groom and the bride, who are united by a ring, in this case by a "que".
I use this worksheet as a reference during the whole subjunctive unite and when they for example forget to write the "que" on a sentence I tell them "You are forgetting the ring" or there is not a "bride" on your sentence, and they quickly remember how to properly write it.
