To be fair, at back to school night our 2nd grade teacher said that the reading log was part of the district's policy of 20 minutes of reading/day, but that if we had a child you needed to nag to get their head out of their book we could skip filling it. And that is was meant as a way for kids to see if they were on track, and as a help for parents to get their kids reading by invoking teachers' authority.
