Zhang laoshi
三零二教室，上午九点。
Sān líng èr jiàoshì, shàngwǔ jiǔ diǎn.
Room 302, nine in the morning.
Xiaoyu
请您慢一点儿说，我记一下。
Qǐng nín màn yīdiǎnr shuō, wǒ jì yīxià.
Could you speak a little more slowly, I am writing it down.
Zhang laoshi

Got it, thank you.

Lǎoshī, gāngcái nín shuō jǐ diǎn ? Wǒ méi tīngjiàn.
Laoshi, what time did you say? I did not hear.
Zhang laoshi
九点。大家别迟到。
Jiǔ diǎn. Dàjiā bié chídào.
Nine o'clock. Nobody is to be late.
Chen Hao
教室是三零二，对吗？
Jiàoshì shì sān líng èr, duì ma ?
The room is 302, is that right?
Zhang laoshi
对。下课以前，我再说一遍。
Duì. Xià kè yǐqián, wǒ zài shuō yī biàn.
That is right. I will say it once more before the end of the class.
This is the request to repeat, word for word: 再 again, 说 say, 一遍 one time through. You soften it with 请 in front, or with 好吗 behind. The full polite form is 请您再说一遍, and it will get you out of trouble a hundred times in your first year.
次 counts occurrences: 我去过三次, I have been three times. 遍 counts complete passes, from start to finish: 说一遍, 看两遍, 听三遍. Repeating a word is 说一次; reading a whole text again is 看一遍. The second implies that nothing is skipped.
慢一点儿说, literally "a bit slowly speak". English puts the manner after the verb, Chinese puts it in front: 大声说, to speak loudly; 快点儿走, to walk quickly. The construction 说得慢, which judges the way someone speaks, also exists but belongs to the next level.
