About 25 minutes, plus any extended practice

Paper or a browser scratch area; no audio recording, account or private information is needed.
The narrator explicitly describes a repeated/background past situation, with subject yo and verb ser (be for past identity/background). Original blank: “yo ___”. Which imperfect form matches? Candidate answers: (A) era (B) eran (C) eras (D) éramos.
The narrator explicitly describes a repeated/background past situation, with subject tú and verb ir (go for a past repeated route). Original blank: “tú ___”. Which imperfect form matches? Candidate answers: (A) iba (B) iban (C) ibas (D) íbamos.

Learn the idea

The imperfect can present a past situation from inside its ongoing or repeated course rather than as one completed event. Compare the narrator’s intended viewpoint; do not replace this distinction with a claim that one tense means long and another short. Ser uses era, eras, era, éramos and eran; ir uses iba, ibas, iba, íbamos and iban in the practiced subjects. These irregular paradigms contrast with both regular imperfect forms and their shared preterite fui-family forms.

Choose the requested verb by meaning first, then match the subject in its imperfect paradigm. Use identity/background for ser and an explicitly habitual route for ir. Keep the written accent in the nosotros forms.

Do not mix era and iba merely because both refer to the past. They express different verbs. A first-person and third-person singular form may be identical; the prompt’s subject and meaning resolve the intended participant.

Copy the supplied example and underline its speaker, noun, time cue or evidence words.
Apply the shown language rule; keep any required ending, accent or paired punctuation.
Solve the changed independent check, then explain why one offered alternative fails.
Complete all three new practice cases and use the model to correct the precise word or meaning.

Worked example

See the method in action

Supplied case: The narrator explicitly describes a repeated/background past situation, with subject yo and verb ser (be for past identity/background). Original blank: “yo ___”. Which imperfect form matches? Candidate answers: (A) era (B) eran (C) eras (D) éramos. Solution: ser is irregular in the imperfect. The named subject yo pairs with era. Shared singular forms do not change the supplied subject, and nosotros retains its written accent in éramos/íbamos. Final result: era. Do not mix era and iba merely because both refer to the past. They express different verbs. A first-person and third-person singular form may be identical; the prompt’s subject and meaning resolve the intended participant.

ibas

ir is irregular in the imperfect. The named subject tú pairs with ibas. Shared singular forms do not change the supplied subject, and nosotros retains its written accent in éramos/íbamos.

Take it further

The narrator explicitly describes a repeated/background past situation, with subject yo and verb ir (go for a past repeated route). Original blank: “yo ___”. Which imperfect form matches? Candidate answers: (A) iba (B) iban (C) ibas (D) íbamos. Expected result: iba. ir is irregular in the imperfect. The named subject yo pairs with iba. Shared singular forms do not change the supplied subject, and nosotros retains its written accent in éramos/íbamos.
