Study / Are English only speaking students accepted into public Wroclaw school? Spanish ones too? [12]

Did you find "English speaking children" friendly public school for your kids? I am moving from States to Wroclaw in May 2013. I am looking for school for my girls grade 0 and 2. I found two very expensive International Schools and one bilingual preschool which offers kindergarten. Are there any other schools which offer primary education in English? I would appreciate any information about schools in Wroclaw.
