It is Monday morning. The sky is blue. My friend and I are going to the playground. There are a lot of students on the playground. Some students are running on the grass. A little boy is running after them. Some boys are sitting on the grass. They are talking. Two girls are flying a nice kite. Three teachers are standing under a tree, and they are watching the students playing. There is a basketball on the playground and two students are playing. Everyone on the playground is very happy.
( )1. How many students are there on the playground ?
