I don't have any nursery rhyme, but I can try to explain the basics: Present tense in English is the same verb for I/you/we/they. The verb add -s for he/she/it (note that some verbs add -es, normally when the verb ends in -o, -s, -sh or -ch) Example: I love, you love, he loves, she loves, we love, you love, they love. Past tense is the same form for everybody (yay!) and regular verbs just add -ed or -d to the main form. Example: I loved, you loved, he loved, she loved, we loved, they loved. Irregular verbs are irregular in the sense that they don't add -d/-ed, but they still are the same form for everybody. Example (past of to see): I saw, you saw, he saw, she saw, we saw, they saw. So, for most verbs you basically need to know if it's irregular, and in that case what's the past form... the rest is simple. There are some special verbs you need to know, which don't follow these rules, but it a small number: - be: (present: I am, you are, he is, she is, it is, we are, they are; past: I was, you were, he was, she was, it was, we were, they were) - have: (present: I have, you have, he has, she has, it has, we have, they have; past: had) - can, may, will, must don't add -s for he/she/it. Their past versions are also special and are not always used as past: could, might, would ... I know it's a lot, but once you understand these basic rules, you are ready to just add more vocab. After you understand this, then you can check the rest of the conjugations, which are obtained by means of combining with auxiliary verbs. Hope to help.

I love Daniel's answer. As far as the irregular verbs, there are around 80 that are very common, so you should google something like "ESL common irregular verbs" -- memorize the common ones first, this is crucial! In order to memorize them, my most successful students simply read out the three forms eg: "take, took, taken; teach, taught, taught; etc." Do this out loud. You should then practice *using* the verbs in sentences to express your thoughts -- on subjects that you find most interesting -- but this rhythmic recitation will always allow you to remember the proper forms when you need to. By the way... I'd love to hear that Italian verb conjugation nursery rhyme....
