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

This sturdy abacus is a valuable tool for early arithmetic learning. It easily guides children to basic calculations for numbers up to 100.

The 10 calculations are clearly represented using the different ball colours (red and blue). Pupils can also familiarise themselves with the power of five.

The initial ball colour is grey, i.e. covered. By rotating it, the ball turns red or blue.

The abacus can be used by 1-2 children at the same time.
Since the plastic balls are recessed in the frame, they cannot be lost.

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.
With instructions and example applications.
