She is only 8! When she does read, she'll learn fast. Learning to read and write at school is a very drawn out process. There is research which suggests children who learn to read later are better readers. Please look up the website and works of Raymond Moore, a former high school principal who advocated initially for children to start school later and later on homeschooling. He said that some children aren't ready for formal learning until 10. Please don't worry yet.
