Building Conditional Forms

Overview

Lesson 2 of 3 in the unit “Spanish Conditional Pathways.” In this 45-minute lesson, 13 students learn how to form regular Spanish conditional verbs and recognize common irregular stems through explicit instruction, retrieval practice, paired problem-solving, and an individual exit check.

Learning intentions

• Students will understand that the conditional is formed with the infinitive plus conditional endings.
• Students will identify and use common irregular conditional stems, including tendr-, podr-, har-, and saldr-.
• Students will practice high-frequency conditional verbs in meaningful phrases.
• Students will reflect on patterns and accuracy as developing Spanish language users.

Success criteria

• I can add the correct conditional ending to a regular infinitive.
• I can form common irregular conditional verbs accurately.
• I can explain that the conditional endings remain the same for regular and irregular verbs.
• I can check my conjugations and correct errors independently.

Curriculum links

• International Baccalaureate language acquisition: understanding how language systems and patterns create meaning.
• International Baccalaureate approaches to learning: communication, self-management, and thinking skills.
• International Baccalaureate learner profile: knowledgeable, reflective, and principled language learners.

Lesson structure (45 minutes)

1. 0–5 minutes — Retrieval hook and learning goals Display a prompt asking: “If you could change one part of your school, what would you do?” Students write one response in English or Spanish, then share possible Spanish equivalents of “I would…” Open with the conditional hook and learning goals. Briefly explain that today’s focus is building the verb forms needed to express possibilities and hypothetical choices.

2. 5–13 minutes — Model the regular formation rule Open the regular conditional rule and worked examples. Model the formula: infinitive + -ía, -ías, -ía, -íamos, -íais, -ían. Use hablar, comer, and vivir, highlighting the unchanged infinitive and bolding the ending. Students repeat the forms once, then complete three quick examples on the guided conditional formation worksheet. Emphasize the written accent in every conditional ending.

3. 13–20 minutes — Introduce irregular stems Use the irregular stem pattern and examples to present the stems tendr-, podr-, har-, and saldr-. Add tener, poder, hacer, and salir as model verbs, then demonstrate tendría, podría, haría, and saldría. Ask students to identify what stays the same: the conditional endings. Students complete a short “stem or ending?” retrieval check on the guided conditional formation worksheet and compare answers with a partner.

4. 20–31 minutes — Structured pair practice Distribute the guided conditional formation worksheet. Pair students strategically, with one student reading the infinitive or subject prompt and the other forming the verb; then switch roles. Include regular verbs such as estudiar, aprender, and escribir alongside common irregulars such as venir, decir, querer, saber, and poner. Partners must explain whether each answer uses the full infinitive or an irregular stem. Circulate, listen for accent and stem errors, and pause for a whole-class correction when a common misconception appears.

5. 31–39 minutes — Retrieval challenge and sentence building Open the partner challenge and discussion prompts. Give pairs a series of subject-and-verb prompts, such as “yo / tener,” “nosotros / poder,” and “ellas / hacer.” Students write the correct form and then create a short, age-appropriate sentence about plans, choices, or hypothetical situations. Invite several pairs to share. Classmates show agreement with a silent signal and explain corrections when necessary.

6. 39–45 minutes — Individual assessment and reflection Students complete the final section of the guided conditional formation worksheet independently: two regular conjugations, two irregular conjugations, and one sentence using the conditional. Finish with the exit reflection and next-step prompt. Students respond to: “Which pattern is secure for me, and which verb stem needs more practice?” Collect the worksheet for formative assessment and preview that the next lesson will use conditional forms in communication.

Resources

• the conditional forms teaching and practice deck
• the guided conditional formation worksheet
• Board or projector
• Pens or pencils
• Timer
• Optional headphones or teacher-recorded audio instructions
• Optional highlighters for marking stems and endings

Assessment

• Monitor partner explanations and listen for accurate use of infinitives, irregular stems, endings, and written accents.
• Use the independent final section to identify whether students can form regular and irregular conditional verbs without support.
• Review the reflection response to plan the next lesson’s retrieval starter and targeted reteaching.

Differentiation

• Provide a conjugation mat showing the six endings, with endings bolded and infinitive or stem separated visually. Model one example before each new task.
• Offer a reduced verb set containing fewer regular and irregular verbs, and allow students to use manipulatives or movable stem-and-ending cards while rehearsing.
• Use an uncluttered, dyslexia-friendly worksheet: sans-serif font, generous spacing, one task per section, clear examples, and optional audio instructions. Read prompts aloud without requiring students to read them publicly.
• Use mixed-ability peer support with defined roles, while extending confident learners by asking them to explain the stem patterns of venir, decir, querer, saber, and poner.

Extension

Students identify patterns among irregular stems and create a mini-reference guide for classmates. The guide should group verbs by stem change, include at least four accurate examples, show the shared conditional endings, and include one original sentence.
