ABACO Class Set for counting in the 100s range, red-blue-grey, 8 pcs., in a box

Three colours and innovative!

The plastic Abaco abacus has rotating balls in three colours to enable differentiation within calculation tasks. With a small movement of your finger to the right, each grey ball can first be turned blue and then red.

This makes it easy to understand counting, complementing and comparing plus adding and subtracting in the number range up to 100.

This versatile abacus is suitable for every learning method and can be used to support any textbook. Since the plastic balls are recessed in the frame, they cannot be lost.

The hundred square is subdivided into 4 sections, each with 5x5 balls. This makes it easy to use, and the abacus can be used by up to 4 children at the same time. Turning the balls is particularly easy, as there is a slight resistance between the changing colours. So you soon notice before a colour is "turned over".

The class set consists of 8 ABACO abacuses for the number range up to 100. They are stackable and can be easily stored in the plastic box provided.
