ABACO Class Set for counting in the 20s range, red and blue, 24 pcs., in a box

This sturdy plastic abacus is a valuable tool for early arithmetic learning. It easily guides children to basic calculations for numbers up to 20.

The square is subdivided into 2 blocks with 2x5 balls for ease of use. The 5 and 10 calculations are clearly represented via 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.

This makes it easy to use, and the abacus can be used by up to 2 children at the same time.
Since the plastic balls are recessed in the frame, they cannot be lost.

The class set consists of 24 ABACO abacuses for the number range up to 20. They are stackable and can be easily stored in the plastic box provided.
With instructions and example applications.
