In the first hour I math class. When I enter the class, I my backpack on my desk. For this class I my notebook, pencil and calculator. The students to bring all the materials. The teacher is very strict. If you don’t your calculator, the teacher will ? use paper and pencil to do the problem. It is very difficult! The teacher always homework on the board. At the end of the class we time to work on homework. Usually I all my homework during class. Then no ? my book to my house in the afternoon.
It is yo trabajo because currently the verb is in infinity form but to put it in first person form you cross out the last two letters and add an o. So trabajar becomes yo trabajo.
