The only problem with postcards is you don't get a lot of space to write... and my handwriting is chunky. #teacherproblems Instead of sending postcards, try sending an All About the Teacher flyer to your students. You can include pictures of you and your family/pets. Introduce yourself by sharing what you love about your classroom and what you are most excited about. Let the students know you can't wait to meet them. Include a list of "Favorites" so the kiddos can learn a little bit more about their new teacher.
What does your school call the day where families come to meet you before school begins? Meet the Teacher night? Open House? Back to School night? Porch Party? Usually they drop off their school supplies, find their classroom, and say hello to the teacher. Every school calls it something different. What is it called in your neck of the woods?
