Thanks everyone for your help and suggestions. Sorry I haven't been able to respond to each one. We have been without internet access since the beginning of October. I have been using the scoreboard since the second quarter of the school year (around the begining of May). My biggest problem is consistency. Thanks for ChrisRekstad for you rewards suggestions. I have been doing something similar to that lately. It seems to help. I have also been using extra credit dextra credit which also seems to be an incentive for quite a few of them.
As for putting up velcro strips, I think it would have the same result as putting up the posters themselves - they wouldn't be there when I returned the next week. Not that the school would ahve anything against it - the students can't resist taking it down just because it's there

- maybe not the kids in my class period, but each classroom is used by 2 or 3 classes at different times of the day - one group in the morning, one in the afternoon, and in one school another group at night. (Fortunately I only teach in the morning.

)
I have been using Teach-OK on occasion, but would like to get into to using it regularly.

Maybe next year.
Lately I have been using some of the activities and techniques in The Writing Game. It has been a life saver! I wish I had had it at the beginning of the year! Any ideas for teaching verb tenses?
I tried playing Mind Soccer with them several months ago. They weren't ready for it, but now after having used the Writing Game I think I will try it again.
Gratefully,
Sister M. Josefa
