It's not really possible or advisable to just suggest a few activities at random. What you need to do is find activities which are ideally suited to your class. That means the activities should both be of a level suited to the class and with content that the class will appreciate and relate to.
So it might be best if we knew more about the class - age, make up, ability, interests, etc and then come up with activities which would fit into their situation.
Making the class fit the activity is the wrong way around; the activity should fit the class.
