This activity is best between and older grade and a younger grade.  The benefits of a buddy system are twofold the older children learn to take on responsibility, while the younger children know that they have a fellow student they can confidently turn to for support.

Buddy systems help to promote friendship and support between older and younger peers through regular collaboration between their classes, creating a sense of whole-school community. They also create friendships that enable both older and younger buddies to bond more closely with their school, increasing the likelihood of more positive school behaviour for all students.​
