teacher

I teach fourth grade and was wondering if any fellow teachers are here. I hate to be gone from school in August. That is when we start here. But I was wondering when should I tell my class. I was going to announce to fellow colleagues and social media on Valentine’s Day. But I wanted to wait longer for my class. I am worried though someone might come in and congratulate or say something my class over hears. When is a good weeks number to tell your class. I honestly have had no symptoms other than cramping. So my class has no clues.
