PLEASE take the time to do this! In fact, I would rather have you do this than a reading or math assignment this week! It's that important. A couple of years ago, I got a letter from a former student (who is now in college!) telling me he still has his compliment letter from 5th grade. This is something you can save and show your children one day!
If you need help with ideas, check out this FILE. It's got tons a compliment ideas.
Also, your name will NOT be attached to your compliment. All compliments are anonymous. You will see the compliments, but not the person who wrote it. That way, you can be really honest and it won't get weird. :)
