Abaco 100 tricolor red / blue

Even more versatile due to its three colors. The new Abaco Tricolor 100 allows differentiation within arithmetic operations with its three-colored turning balls. With a small finger movement to the right, each gray invisible ball can first be transformed into a blue ball and then into a red ball. This effectively illustrates counting, complementing, comparing, as well as adding and subtracting in the number range up to 100. The Abaco Tricolor 100 devices are suitable for 3 to 4 children.

How is the Abaco counting and calculation frame used in the classroom? The calculating device is a very versatile tool in mathematics education. Your students can independently perform the following arithmetic operations and then also check their work: discover patterns and regularities, find numbers on the hundred chart, name the predecessor and successor of a number, conduct number dictations, recognize quantity relationships, partition numbers, solve and verify calculations, and play dice games with ten and one dice.
