I have a question and am hoping you all can help me. In the past our PTO has given the teachers a blank check to pay for admission on field trips. The PTO pays $7 a child (bus and admission) anything above that amount the families pay. The teachers request a blank check because the say they don't know how many kids are going until that day (i.e. some might be sick, some pay their part that day, etc.). What do your schools do in this type of situation? Do you give blank checks for field trips?
