More anecdata: my younger two are bilingual and didn't know how to read more than really basic sight words before starting K (common core class). They are now highly proficient at reading (english), which (they are decent learners and have no challenges) I reason are due to two things: 1) An interest in reading which is fostered by the class atmosphere - they have "choice" time and some of that can be reading. 2) They have an expectation in class to spend a lot of time reading or being read-to.

I will admit we did read to them every night since they were babies, so that's probably also helpful. But kids usually love the bedtime story.
