Yes you can definitely extend the learning. The benefit I like the best is if she is really struggling with something... We don't have to move on until she's got it an we can really focus on what she is having difficulty with. That was a big one for me in school. There were things I really had difficulty with but they can't hold up the whole class for my difficulty but then they'd move on and I was totally overwhelmed. My mom tried tutors but by the time I was done school for the day, I was so upset and burned out that I was totally resistant to anymore school.
