Hi Rochelle:
Keeping a tally sheet is a good idea, as it does help the student keep track of their individual performance.
I would say that frequent sharing of grades (comparing in your case) is important because our persoanl connection with the student gets strenghtened, and we can relate more normally. Also, it gives a chance to encourage, giving support and offer care and/or demonstrate comfort or concern, and give advice to improve results.
