Classroom Expectations

[a] Rules

  1. Be in your seat when the tardy bell rings with HW out.
  2. Stay on task until the class is dismissed; hence, no phones, no earphones/earbuds, and no other unauthorized electronic device usage.
  3. Listen and follow directions the first time.
  4. Obey all school rules.

I reserve the right to clear calculator memory at any time.

[b] Electronic device expectations

You may use an electronic device only with permission for a specific academic purpose. If your phone  or earbuds are visible during class, you will be assigned detention.  Furthermore, do not charge your devices in the classroom
