5. We read a little in class.

Nosotros leemos un poco en la clase.

Explanation:

Nosotros means we. Now you don't actually need the word, it is best to add it to the sentence to make it the most clear it can be. Leemos translates to we read. You can start with this word if you want, but the most correct would be to add nosotros in front of it. Un poco means a little. En la clase means in the class. In Spanish, the article is used much more than in English, so la(feminine the) is added before clase.

well, if he says unos it is 1, if he says dos, it is 2, if he says tres, it is 3, if he says cuatro, it is 4
