Just wanted to let you all know (sorry for the repeat, Barbara!) that we just launched a new unit that covers these verbs, along with other irregular verbs, in the simple past tense (pretérito perfeito).
If you go to the main Units page, it’s the Simple Past 2 unit near the bottom of the list. The last few lessons cover, ver, vir, and then ver and vir together.
(For now, the verbs section is the best way to get practice with the other tenses.)
