I make sure that a fire drill is practiced with the class early in the very first week of school. With them all being new to school, I want to ensure that they know what to do, so they will not be traumatized by either a drill or the real thing. Later in the year, subsequent new children will follow their more experienced classmates, but those initial February babes don't have that benefit.
Forever curious, always learning, deep thinking teacher. I am a Year 5 teacher this year and am enjoying the transition after 3 years with New Entrants.
