The absolute best way to contact me during the school day is by texting. It is totally fine if you need to tell your child to "go to aftercare" or some other time sensitive issue to text me to my personal phone number.
I use Fast Direct for important announcements for the class and scheduling appointments.
In person communication: We will meet for our annual Teacher Conference in November.
Open Door Policy: I usually am available after school until 5pm, as I stay late to finish my work and prepare for the following day. If my door is open after school, please feel free to come say hello or communicate concerns/questions if necessary.
