Bead and abacus toy2/12/2024 ![]() The paper helps children write down the quantities on the wires correctly. This allows the children to begin making the transition from the concrete representation of numbers through materials to the abstract representation on the paper. In addition, the Large Bead Frame comes with special paper, sensibly named Large Bead Frame Paper, which repeats the color and family pattern, and even contains special lines meant to represent the wires that hold the beads, though the entire setup is turned 90 degrees so the wires go vertically. So far, not only have we materialized the concept that every decimal category holds ten elements, but we have also materialized the complex pattern of the decimal categories themselves, something that children can have quite a bit of trouble grasping. The colors repeat in groups of three in order to emphasize the repetition of the “units, tens, hundreds” pattern within each decimal family. Moreover, the left-hand uses three shades of gray, which group together the different families of decimal categories: the simple family (units, tens, hundreds), the thousands family ( units of thousands, tens of thousands, hundreds of thousands), and the millions family ( units of millions, and we could continue with tens of millions and hundreds of millions).įurthermore, the coloring of the beads is not random, and is not there merely to be inviting. On the left-hand side, the decimal categories are explicitly written out in numerals: 1, 10, 100, 1,000, etc, making it clear to the children what quantities each wire represents. The abacus toy does do this to an extent: the beads can represent decimal categories (units, tens, hundreds…) in the base-ten system, hence the ten beads on each wire, but the base-ten system isn’t explicit. ![]() They are “materialized abstractions”, that is, they are meant to embody the mathematical concepts under consideration in a clear physical form. Montessori math materials are far more than simply calculating tools (in fact, some of them can’t be used for calculation at all!). Both can be used for adding, subtracting, and with some cleverness, multiplying whole numbers up to the millions or so, and so both could be considered mathematical tools for calculation. Both are wooden frames with horizontal wires or dowels that each contain ten beads. If that were the only reason, it would be a pretty silly distinction.įirst, let’s look at the similarities. To the untrained eye, they look quite similar, and it’s not necessarily obvious why one should be considered a “Montessori material” and the other shouldn’t, beyond the fact that one was designed by Maria Montessori for use in classrooms. Now there is a Montessori material that looks similar to this: the Large Bead Frame. I have even seen photos of them in marketing materials for schools that purport to be Montessori or Montessori-based. ![]() In this occasional series, we will look at various materials and methods that are often advertised as Montessori, to see how well they embody Montessori principles.įor this first edition of “Is It Montessori?” I’m going to indulge in a bit of grumbling about a personal pet-peeve of mine, namely those brightly colored abacus “toys” that are often advertised as Montessori math materials.
