Poor students need funding to build schools and learning materials

This is a open school in Sirajganj, Bangladesh. One of my friends started this school. The poor children in this school are free to study. Every day more than 50 students come to study here. But they are studying at a open field. It is necessary for them to build a school. Because they suffer very much in the rainy days. Even in the winter they are very much in trouble. If everyone comes forward with the help of these poor children, then they can develop their own life by studying. Seeking cooperation of everyone. Thank you
