I do have my children reading more than that. For example each of my children has a literature book they read for at least 30 minutes (summer) or 20 minutes (during the school year). They read science related stories. They read about artists or composers or inventors.
hsmom22 – it depends on your family’s approach to science. Yes, by 4th grade you can have the child reading their science books on their own. We’re doing science with the 7 youngest together this year so I’ll read it aloud to the group. They’ll then have a basket of related stories and books they can pull from to enjoy on their own.
