4th Grade


Welcome fourth grade families!  We are so excited to have you “here” at STEM Launch!

A Little Bit About Us . . .

Ms. Calus and Mr. Calus have been teaching 4th grade at STEM Launch since it opened in the fall of 2012.  Prior to that, they were both fourth grade teachers at Federal Heights.  Mr. and Mrs. Calus have two daughters.  Both of them attend STEM Launch.

Ms. Challman came to STEM Launch in 2016 as a student teacher in 5th grade.  We were lucky enough to keep her on staff as a 5th grade teacher.  She moved to the 4th grade team in the fall of 2018.   Ms. Challman has a puppy named June that is 1 year old and 2 cats named Mala Suerte and Charlie.

Mrs. Smith is our bilingual English Language Development teacher.  She has been with STEM Launch since 2018.  This is her first year on the 4th grade team.  We are so excited to have her expertise.  

Virtual Learning

As I am sure you are aware,  we will be starting this school year virtually.  We will be using two platforms, Schoology and Florida Virtual Learning.  Florida Virtual Learning is new for all of us.  As teachers, we have experience taking classes using Schoology. Leading classes on Schoology will be new to us as well.  We appreciate your patience with us as we try to figure this all out. 

Students will be expected to follow a schedule as if they were in class at the building.  You will find that schedule below.  

There will be a mix of synchronous and asynchronous learning, meaning there will be times students will login to Google Meet for a live lesson and times where they will be working independently.  Your child’s teacher will host a morning meeting everyday at 8:15 to cover the schedule, any changes and expectations for the day.  Teachers will also post information in Schoology for students.  Parents, you can expect a weekly update via email, ClassTag and/or Facebook based on the preference you chose in the Parent Survey.
