Arithmetic Bead String (approx. 45 cm) with 20 balls, which are threaded in steps of 5 on a tear-resistant, stretchable cord.
The balls are made of RE-Plastic and have a diameter of 10 mm. When the string is pulled, the light ball lock is released and all the beads slip back together.
Since the balls have the exact diameter of 1 cm, they are also suitable for calculating and measuring.

Super praktisch
super praktisch um die Zahlzerlegung bei Kopfrechenaufgaben mit 10er-Übergang zu festigen. Die Kinder sprechen parallel mit während sie die Perlen zur Rechenaufgabe bewegen.
