How do you welcome students back after a long vacation/break?

One thing that I hear teachers say is that they do not teach to the test. I feel that if the test is assessing the standards, and you are teaching the standards then you should teach to the test. I use the released test to show the students how questions are worded and how to look for patterns in the format. I liken the test as playing a game. The more a person knows the rules of a game, the better they will do. Likewise, the more a student understand the testing structure, the better they will do.

Consider a teacher who wants to introduce a text that includes content that might be sensitive or upsetting for some students. How should the teacher prepare to address potential issues that students might have due to their prior experiences, while also fostering a sense of safety and respect in the classroom? What steps would you recommend for the teacher to take in order to ensure that both students and parents are adequately prepared for the content of the text?
