100 Bead Slavonic Abacus
The arrangement of beads on the Slavonic Abacus supports children’s ability to easily recognize up to 5 beads in a row without counting. This is then extended to seeing the pattern for numbers to 10 and then 100.
Students can use the abacus in either an upright position or laid flat on the desktop.
The frame and beads are made from reconstituted wood.
Frame size 170 x 245mm, beads 13 x 11mm.
Made in Germany.
