Using journals in Kindergarten? Not sure what this looks like?
This freebie has pictures to give you an idea of how to get started (specifically in the beginning of the year when the students are not very independent yet).
I also included a few printables to get your started. I hope this helps you with the concept of journals/notebooks/portfolios in Kindergarten!
