20 bead string red/blue
Average rating of 5 out of 5 stars
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.

- count forwards and backwards from 1 to 20
- grasp quantities at a glance
- decompose quantities (7 decomposed into e.g. 5 and 2)
- count in steps (e.g. 2, 4, 6, ... or also 17, 15, 13, ...) even or odd numbers, neighboring numbers
- compare numbers (>, < or =)
- add (plus) and subtract (minus) numbers in the range up to 20
- multiplication / division (doubling / halving)

Review with rating of 5 out of 5 stars
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.
