At this age, kids find themselves in a transitional phase, since they already got a first taste of what school and following rules mean. They have a better sense of their limits and capabilities; they experience a more intense kind of independence, whilst they develop further their personality, preferences, taste, and friendships.
Toys that require collaboration and following rules are:
Action and family board games
Electronic educational games
Ability to jump on a straight line, hit the ball and catch it again.
Ability to occupy themselves with something specific for more than 30 minutes.
Ability to have a conversation like adults would do and understand fair play.
