Peekapak is flexible, and can be used during any period including English, Health, or a designated SEL time.
For a split class, use Peekapak as you normally would treat any other subject where there is a split class. You may also consider the child's SEL competency level rather than grade and group together kids from different grades. Some parents may wonder why their Grade 3 child is with Kindergarten or some kids may wonder why they are mixed in with younger kids – Educators can advise they are teaching in a multi-age setting which is what happens in the real world and allows for cross pollination of ideas across different age groups and experiences. It is rare to be in an adult setting where everyone in the class is the same age.
There is also a way to create two separate groups on Peekapak for each grade so they can access different grade level content and tailor their lessons. This is super helpful for after school programs but also split classrooms.
