*Due to teacher duty assignments,
student detention may sometimes
have to be assigned to after school.
st
*Attendance is important. According to the Atkinson County Middle School
Handbook, students may not receive credit for any class for which they have
excessive absences that are not excused. Remember to bring an excuse each day
you are absent and turn it in to the receptionist in the front office. Be sure to get
doctors’ notes explaining the reasons for absences. Be careful about leaving
school early during your 6th period class.
The curriculum for 8th grade mathematics has rigorous content to enable students
to be able to think more critically about solving problems. Students are expected
to explain in writing the processes they used for solving problems. They are
expected to show a deeper understanding of the concept. According to the
standards, just “showing work” is no longer enough. The curriculum now taught
is governed by Georgia Performance Standards. By the end of this year, students
will have been taught each of the Georgia Mathematics Performance standards.
