The Tabletop Abacus is a Montessori material designed to help children develop a solid understanding of basic arithmetic, particularly in the areas of place value, addition, subtraction, multiplication, and division. Unlike smaller hand-held abacuses, the Tabletop Abacus is larger and often features a frame with multiple rods, making it suitable for use on a table or flat surface. It is typically made of wood, plastic, or metal, offering a sturdy, easy-to-use tool for young learners to explore mathematical concepts in a concrete and hands-on way.
