After teaching about the String Family, I had the students get into 5 groups. Each team received a picture of one of the stringed instruments, a dry erase marker, and eraser. They were asked to work as a team to write as many facts about their instrument as they remember from the lesson. They also enjoyed labeling the various parts of their instrument.
I found that this was a great way to incorporate team work and also assess what they had learned from the lesson. Once each group was done, they shared their facts with the class and posted their instrument on the board for everyone to see.
