If the school allows, call and arrange for a visit. Meet the principal and visit the children's classrooms. Ask about necessary materials and the school's policy for providers visiting. A copy of the school calendar will allow you to plan for vacation days. In our area, school is released for a half day every six weeks for a teacher's work day.
Schedules also vary for exams.
Just a simple change in a child's schedule can create chaos. Having this information helps a parent and a child care provider to make the necessary changes. Be creative and embellish the story. If you cringe at storytelling, check out books from the library written about children and school. Support your children and support the school.
