Translation of spasm in Spanish

What do we do about the numbers? I skipped them because I wasn't sure. Because it is possible that somebody wants to know how to say 15 in Spanish. He should write out the word as 'fifteen', not as digits.
The words will mostly be easy. I would prefer full sentences and not just short clauses with the article, the noun and an adverb/adjective. Do you think you could do 1000 sentences per working day? This way we could finish quickly.
I once had a lesson with a private teacher, but unfortunately she could not come regularly. She was always sick, then I have visited a school in Andalusia, which was worthless, since we talked only German.
