The Teen Bead Hanger (C208) is a key primary-to-lower-elementary transitional material that supports children's understanding of the linear counting sequence from 11 through 19 using the colored bead bars hung on a wooden frame. It bridges the concrete work children have done with the number rods and golden bead material by making visible how each teen number is composed of a ten-bar plus additional units. Keeping this material accessible on your math shelf allows children to return to it independently as they solidify their understanding of place value in the tens and ones.
