You can say that with group work the negatives can be that, sometimes only one person is working on the assignment because no one else wants to. In group work the whole assignment can be thrown on one person because the rest of the group will not contribute. I have experienced this before where I had to do a whole project by myself because my group would not help. The positive about doing group work is that you can work with other kids so you can have a great assignment. When you work with others you can brainstorm ideas, and share knowledge. Teamwork would be working together with your team. For example in sports a team works together to win the game. Without team work how can you give your best and win? I hope this helps and sorry this is not three paragraphs.
