I explained to the reader that some children show extreme interest in Mathematics and will choose lessons like the Hundred Board daily. I perused my school pictures and found a child enjoying the Hundred Board. Placing the small tiles on the board is called the "Point of Interest" in the lesson. Each Montessori "work" has a Point of Interest that captures the child's attention, whether it's a clinging sound, a shiny bowl, or a tiny object. This particular three-year-old truly enjoys small objects and sequences of numbers, therefore the Hundred Board is just right for him. I'm looking forward to giving him the extension lessons on this work- placing the odd or even tiles and placing the tiles in a spiral.
Maybe he's also experiencing a Sensitive Period for hoods? :)
