By the end of this lesson, students should be able to:

• Recognize and correct the incorrect use of e-I stem-changing verbs.

Lesson Flow

Introduction (5 minutes)

Engagement Activity:
Begin with a brief review of e-I stem-changing verbs. Ask students if they can recall any examples, such as "pedir" (to ask for), "servir" (to serve), or "competir" (to compete). Write these on the board and display their correct conjugations in the present tense:

• Pedir: pido, pides, pide, pedimos, pedís, piden
• Servir: sirvo, sirves, sirve, servimos, servís, sirven

Highlight the pattern change from e to i. Explain that they will be applying this knowledge to correct a story today.

Activity: Story Correction (15 minutes)

Instruction:
Distribute the printed story with 15 misspelled conjugation errors among the students. Each student or pair of students will receive a section of the story.

The Story:
Here is the story with intentionally incorrect verb conjugations:

---

"La familia de Juan pedies una pizza cada viernes. María y su hermana se sirven de ensalada primero. Cuando el camarero compite para tomar la orden, él no sonríe. Yo pedo la pizza con muchos ingredientes. Mis amigos preferís la pizza de queso solamente. Nosotros servimos el refresco en vasos grandes, pero ellos sirvis helado después. Tú no pido permiso para salir porque ya eres mayor de edad. Cuando la comida llega, todos decimos gracias, pero el camarero todavía compito por atención. Después de comer, yo sivo el café mientras ellos pedimos la cuenta. Por último, cuando el camarero trae la cuenta, mi madre sugiere que paguemos juntos. Mis padres accedes, aunque a veces complican las cosas."

Group Correction and Discussion (5 minutes)

In pairs or small groups, ask students to discuss the inaccuracies they identified. Each group should write down the corrected versions of the verbs.

Class Review (5 minutes)

Invite each group to share some of their corrections with the class. Correct mistakes as necessary and write them on the board. Use this opportunity to reinforce the correct conjugation rules for each e-I stem-changing verb.

Conclusion

Summarize the key points of e-I stem-changing verbs, emphasizing patterns and common mistakes to avoid. Highlight that mastery of these verbs can help with more fluid and accurate Spanish communication.

Assessment

Assessment will be informal, based on participation in the group activity and contributions to the class discussion. Listen for correct verb conjugations during sharing sessions.

Extensions

For students who need further practice, introduce additional verbs like "repetir" (to repeat) or "medir" (to measure) with similar exercises. Encourage students to write their own short story or dialogue incorporating these verbs.
