I would love a display like this in my future classroom! Each child's name would be written on a clothes pin and they would be in charge of choosing which work they would like to display. They could pick the one that they are most proud of to show off, to show off their hard work.
Student paperwork filing system - I think I found my solution for student portfolios. The Container Store's crates available in various colors will be perfect for this!
This is a great way to display student work and utilize the dead space of a window...maybe book recommendations? Looks like it's held up with a curtain rod. Easy to change out by attaching each piece of writing or drawing with a clothespin!
