Here is our most recent sensory bin. It includes a pack of farm animals from Walmart that also came with the fences and trees, a Little People tractor, and the filler is spanish moss from Dollar Tree.
My little man loved the tractor the best. He is a huge fan of cars and anything with wheels.
He also liked pulling apart the pieces of spanish moss.
I liked the spanish moss as a base for this sensory bin because it resembles hay, but I can also see using it for lots of different kinds of sensory bins.
If you would like some more resources on this topic, see past posts on farm activities, farm books, and more farm books. Here are some books to go along with farm animals:
What kind of sensory bins/tables have you been making?
