DAVID'S LAW: If you see something, SAY something!

If a student believes they are a victim of cyberbullying or if you have knowledge about an incident of cyberbullying, you can report it using RRISD's Anonymous Alerts. Anonymous Alerts allows students/parents/teachers to submit any sensitive or urgent student issue quickly to school officials. Students or parents can submit reports such as bullying, cyberbullying, depression, dating violence, drug or alcohol use, threats against the school, weapons on campus and more. All messages submitted remain completely anonymous.

Extra Help:

If you are ever struggling with a concept, please see me for extra help during tutoring times or you can schedule an appointment for another time that works better.

  • Tuesday Afternoon 3:35-4:15 PM
  • Wednesday Morning 7:45-8:13 AM
  • By appointment all other times

What if I am Absent?

Daily Lesson Slides & Homework Assignments are posted in Google Classroom. If you don't have access to a printer at home, simply let me know and I'll be glad to print a copy out for you.

It is YOUR responsibility to pick up absent work and schedule a tutoring time to get caught up.

Late Work & Corrections:

  • To receive credit for late assignments, a Late Slip MUST be filled out and turned in to me.
  • IXL assignments: IXL's done on time to the required SMART SCORE (usually 80) are scored 100. Late IXL's will receive the SMART SCORE as the gradebook grade.
  • Homework/Daily Grades: A deduction of 10 points per day will be applied to any assignment turned in after the due date and a Late Slip must be signed.
  • Test corrections: Test scores can be raised to a maximum of 70% if corrected. Corrections MUST be done on the Test correction page (NO EXCEPTIONS).

*** All assignments must be turned in before a unit is complete in order to receive credit***
