Differences Between The Present Subjunctive Mood and the Future Indicative Tense
Students often require extensive practice of The Present Subjunctive in order to distinguish the way it differs from the Future Tense in Spanish, since both seem to be used to describe an action in the future.
The most successful approach I have used in the classroom in order to compare The Present 텐가 Subjunctive and The Future tense in Spanish is not necessarily to explain Grammar over and over again, but to write several sentences on the whiteboard and guide the class into deep analysis of each one. It is important to encourage students to share their perception regarding the differences they find in each sentence.
After continuous analysis of sentences, students conclude that The Present Subjunctive Mood refers to the situation that is yet to be experienced, and they can tell The Future Tense is what we have already planned to do when we finally experience the event.
-I will buy a house when I win the lottery-
-Yo voy a comprar una casa cuando me saque la loteria.
That I win the lottery is yet to be experienced while buying the house is the one thing I have planned to do when the unexperienced event occurs.
-I will help you decorate your room as long as you promise to keep it clean and organized-
-Yo lo/la voy a ayudar a decorar su cuarto siempre y cuando me prometa mantenerlo limpio y ordenado-
