Yesterday I was able to stop by the Observation Window outside of Humphrey's class and I caught her totally immersed in work. She was at a table working in the Hanging Bead Stair.
I saw her pick up a bead bar, she would touch each bead and count aloud. It was great to see her--one, two, three, four, five... Once she would count the correct number, she hung the bead bar on the appropriate hook. Following through and completing her work.
She is into "Challenging" work these days, but usually saves them to do in my office before or after school. Today while Magoo was napping, Humphrey decided to work on the 100 Board. This material falls under linear counting in the Montessori math curriculum. Putting tiles of numerals 1-100 in order on a grid board.
