100 Arithmetic Bead String by Wissner

100 Arithmetic Bead String by Wissner features 100 red and white beads divided into groups of 10. The bead string is a fun way to teach children how to count, add, subtract, multiply and divide.

The string is approx. 150cm and is tearproof, stretchable string.  When pulling the string, the slight ball lock lifted and all beads slide back together again. Each plastic bead has a diameter of 1cm and therefore the bead string can be used as a tool to measure. Age 3 – 10 years.

100 Arithmetic Bead String by Wissner is an educational product and not a toy. It is packaged in a bag. Not safe for under 3 years.

The string is black not white as shown in the photo.
