These seem like well focused, achievable goals, Abigail. As you meet with students each day you undoubtedly will learn a lot about how your school actually works. You will also create expectations that you will take action. This can be a double edged sword, particularly if students begin to use these meetings a mini-grip sessions.
I also urge you to be vigilant to identify students who are disenfranchised and don't participate in the appreciation activities.
Good luck; let us know how these actions work.
