Be sure that you are monitoring students in the classroom on an equal basis. Don't focus too long on any one student, especially the ones who are extremely eager to answer questions, as those are the ones you will probably naturally gravitate towards. we must remember to treat all students with equal attention and respect.
When putting students into groups, aim for group diversity. Don't lump all of the top students together. Mix up the groups with overachievers, and people who are struggling a bit. This will help everyone involved, as the better students will get more experience through helping the ones who are taking longer to learn.
