Number tiles offer a flexible, small-footprint material for composing and decomposing numbers, building equations, or supporting place value work across the early childhood and lower elementary continuum. Because they are discrete and recombinable, they lend themselves to open-ended lessons and child-initiated exploration in ways that fixed materials do not. Teachers will find them particularly useful for differentiation, as the same set can serve a child working on basic addition and a child exploring early multiplication or skip counting.
