This is our Halloween sensory box from last year. It stored very well and the kids really enjoyed getting it out with the rest of our Halloween decorations. The base is dry black beans. The other things placed in here are fall items that can be found at the dollar store--erasers, little pumpkins, stickers, plastic leaves, etc. With this box, we have a silicone pumpkin tray. The kids play sorting and counting games with this sensory box. For example, I will tell them to find as many candy corn erasers as they can and then count how many they found. Other things we have done are to sort through and pull out anything purple, or find 5 cat erasers, etc.
