About This Product
Overlapping rings turn abstract set language into something pupils can see. In elementary classes the rings are used for grouping, while higher secondary students use them for set theory and to demonstrate Venn diagrams, where the overlapping region holds the elements two sets share. Having two rings in each of three colours allows several sets to be shown at once, and every ring is foldable. Schools and distributors in Cameroon, Bosnia and Herzegovina, Sierra Leone, Timor-Leste and Moldova can order the Sorting Ring from School Educational Instrument.
