It's a nifty little tip I learned from a local Montessori teacher. When children are counting using bead chains, it might be easy for them to lose their places or miss a bead. Even 3 year old fingers are bigger than the bead chain beads. What to do . . .
The little closure pieces from store bought loaves are bread are the perfect size for little counters. Here's one of mine I just took off a bag.
I cut it in half,
and tah dah, I have two little bead chain counters. They are just the right size for little fingers, and the half circle opening just fits in the spaces between the beads.
