Parents, read to your kids!
Good advice for parents. These stats (read the full article) by implication also point to the importance of library time for Primary students. Access to books, being read to, and developing a "culture of readers" has huge consequences for success in later life.
"A typical middle class child enters first grade with approximately 1,000 hours of being read to, while the corresponding child from a low-income family averages just 25 of those hours, such differences in the availability of book resources may have unintended and pernicious consequences for low-income children' long term success in schooling.
