At age 8, most children need some structure to remember to turn in homework. Sounds like you are not having a problem getting the homework completed. Great! If you don't want to give the reminder every day, how about posting a note on the door where your child leaves for school. Something visual, eye-catching, cute, and funny would be best. You could cut a picture out of a magazine. If this doesn't work by itself, you might want to make a weekly chart and have your child put a sticker on it just before he or she leaves for school as a reminder. As a last resort, you could add a reward system to the chart. For every week where your child has say 3 of 5 stickers, he gets to choose an activity from a list you generated together (special time with a parent often works; playing a board or card game for 30 minutes, going for a walk, getting ice cream, etc.). Once the homework leaves the house, you could ask the teacher to temporarily help make sure it's turned in if needed.
