Good morning!
Please get unpacked and be seated by 8:50 for announcements
Extension period - block A
today ıs an "a" day, we have gym
Yankee Candle Fundraiser for Homeless Animals We are asking homerooms to select one student to represent their class on Student Council. A main criterion for interested students is their availability to attend monthly meetings on Wednesday mornings. The meetings will begin at 8:00 AM. We are looking for students who are hardworking, responsible, and dedicated.
Please click on the link below and input in your representative by September 19th. (similar to what we do for MVPs)
https://docs.google.com/a/ltps.info/spreadsheet/ccc?key=0AstoU8Lw5fupdFBsV1NRSTRVNGJqTmw0b2dGQXJtRVE#gid=3 Please input any Current Officers elected last June that are in your classroom. If you have an officer in your room, you may still have a class representative. Students who ran last year are NOT automatically reps on Student Council.
Thank you very much for your cooperation! On Tuesdays leave chairs down, so the custodian
can clean the desk tops.
tomorrow will be the beginning of the year test
