My 1st week and a half

Over the last week and a half that I have been out in the field, I have learned so much from my CT and students.  One of the most rewarding experiences I have had so far is working one on one with a student who knows very little English.  My first day in the classroom I began to notice the student was turning in blank papers.  Since then I have been working with her one on one in math.  The class is learning about money and they all brought in bags of coins to practice counting.  What I started doing after the student understood what a coin was worth was point to it, say the name then student always repeated it.  After a week of this, today in class she went to the smart board and pointed to a coin and said "Nickel!" and wrote how much it was worth underneath correctly.  I was so proud because nickel had been a word she had struggled with saying.  Another thing the student struggles with is writing numbers.  My CT told me the ELL teachers teach specifically speaking and writing words; they don't teach them how to write numbers.  I recently have started on her worksheets been having the student trace the numbers.  It’s just so rewarding to see students master a task after watching them struggle for so long.  Is anyone else working with ELL students? Does anyone have any ideas on how to help them learn?
