J.S.
I say go on your trip and enjoy every minute of it, BUT tell the school the truth and nicely talk to the teacher(s) about getting the work that will be missed. The teacher might not be required to get it early for you (you might need to wait until after your trip), and your daughter may not receive credit for doing it, but it is very important for you to set a good example for your daughter. It is imperative to tell the truth and take responsibility for your actions. Fortunately, your daughter is still young and it should not affect her academic career.
