A wooden unit bead stand with nine indentations on one side (and one indentation on the reverse) for holding unit beads in place

The block shows how the decimal system changes hierarchy at 9, so children learn that after 9 units the next number is 1 ten which is made up of ten units etc.

These full size Séguin teens boards teach the child the number names, symbols and sequence from 10 to 19. They are ideal for use with Montessori beads.

NOTE: tens boards are not included

The two wooden boards have 9 number slots each labelled with 10 and the child counts up sliding the wooden digit cards 1 to 9 into these slots.

The numbers 11 to 19 are particularly difficult for a child to learn as their names are more complicated than those of the rest of the number system. The teens board helps to develop a true understanding of how these numbers are formed from a ten and a unit, and thus teaches the foundations of our decimal system.
