Children at aged 2-3 start to play with others, they learn to share toys and food. Under adults' guidance, children start to have pretend play and group activities. In Catiline, we purposely design activities such as BBQ, roll the boat etc. to encourage cooperation between children. These activities help children with their social skills, moreover, to understand themselves and the others, building up a positive self image. This is a key element for their character development.
