Object Permanence Box
The single most iconic Montessori baby material, and it earns it.
Independently selected. We may earn a commission in future, at no cost to you. Price is approximate.
Our take
A ball goes in the hole, disappears, then rolls out the tray, and a baby's whole face changes the first time it happens. This is the material that teaches object permanence concretely instead of abstractly, and it holds an eight-month-old's attention longer than almost anything else on a shelf. Get the version with a wooden ball and a flat tray, not the multi-shape upsell.
