For outdoor activity we set a big and complex wooden structure with many bars and stairs on different levels and different angles. Kids should do their best to keep the balance and watch their every step. 

Before to start we asked kids to form a line and gave them some behavior rules. At every stage of this structure was a teacher for kids support and safety. 

They were crossing it crawling and walking, having a lot of fun and overcoming fear of falling. 

This is a great way to keep the growing body in a good shape cause it involves all muscle groups.
