Start with the basics. Begin with pronunciation and simple vocabulary, such as greetings or ordering food. Lay the foundations for developing a more complex understanding of the language from the get-go.
Practice with role-playing and scripted conversations to help students practice their conversational skills. Improvised conversation is challenging for new Spanish speakers because they may lack the vocabulary to fully flesh out their thoughts. However, scripted conversations provide excellent examples that fill in the gaps and improvised conversation allows students to see what parts of their vocabulary need improvement.
Practicing writing letters and labeling items around the classroom gives students visual aids as they are learning everyday Spanish vocabulary.
Spend extra time on the parts of the Spanish language that can be especially difficult for English speakers. According to MASCI, a Spanish education and consulting group, most English speakers stumble on learning the concept of gender and the differences between "ser" and "estar."
Expose your students to Spanish and Latin American culture. Use television and movies for better aural comprehension and have cook nights where students speak Spanish and create dishes from Spanish-speaking countries to keep classes hands-on and fun.
