This is the bead and dowel activity I was mentioning. We finally acquired a 5/16" drill bit, so I was able to throw this together yesterday evening for use this morning.
I just took a piece of 1" pine I had and drilled a hole as big as the dowel. I cut the dowel to a seemingly-appropriate length and Gorilla-glued them together.
Nugget went right for this one. I intend to grow this into a pattern-following activity (giving her pictures of bead stacks for her to repeat), but for now it's a great fine-motor activity to put the beads on the dowel.
I need to tweak this by sanding the dowel smoother -- it's rough at the top, and some of the beads with smaller openings stick and cause frustration.
For now, though, it's a hit. She's gone back to it a few times. And pulling the beads off -- and dropping them on the floor to bounce around the nook -- seems to be fun, too.
