A better classroom

Hello I am an English teacher currently living in the Yucatan peninsula in mexico.
This year is my first time as an english teacher and i am thrilled to have finally been given the opportunity to teach in an elementary school. It's been going well ever since august but there are a couple of things that the children need so i can teach even better. My pay is low and i can't help out much, my rent and food really drains my pay a lot. I earn 2,460 pesos bi weekly. It isn't much. My intention is to get some supplies and a projector for the time being. I have tried to borrow a projector from the school but there is only one and it gets shared from school to school and to teacher to teacher and it's very frustrating having to wait 2 maybe 3 weeks and then when i need it again it's just a hassle.
I just want the kids to learn and have fun. I've always dreamt of becoming a teacher and helping others. I just hope that i get this chance.
Thank you for your attention and time!
