THIS IS THE WRITING:

Dear Superintendent of Schools:
I have (usually we don't abbreviate verbs like this in a formal letter though your abbreviation was correct) recently read an article in "The City Times" about after-school music and art programs that have been canceled, so I’m am writing to give you my opinion about this. As Like many parents, teachers and students, I criticize object to this because some for the following reasons I’m going to write below.
Art is necessary not only for students and also but for everyone every people is necessary because it gives us the chance to tell the world we can do something incredible.  and also it’s It is also important to in developing the imagination. If Black Rock Board of Education is cancelling the music and art programs, how will it teach students to be creative? (or to do something that people would like?

Something more that I can say is that why Furthermore, if teachers are going to receive a pay raise next year, why do they cancel the programs?

Sorry if this looks a bit messy!!

Dear Superintendent of Schools: 

I’ve recently read an article in The City Times about how after-school music and art programs will be canceled, so I’m writing to give you my opinion about this. Like many parents, teachers and students, I object to this for the reasons I’m going to write (It works better if you don't say this) below.
The art is necessary for students and also for all people because it gives us the chance to tell the world we can do something incredible and is also it’s important to develop the imagination. If Black Rock Board of Education is cancels the music and art programs, how will it teach students to be creative or to do something that people would like? The board should really think on that.
Also, why, if teachers are going to receive a pay raise next year, should they cancel the programs? They say they are cancelling the programs to reduce spending but ironically they are going to be better paid next year. I think they just want good vacations and be relaxed but they are not thinking about kids and what they need to learn after school.
In conclusion, what Black Rock Board of Education is doing is terrible for kids so it should think again about its decision.
