10-bead support abacus (Tomoe Abacus)

Counting before calculating with paper and pencil is the best way to develop a sense of numbers. This support abacus was created for that purpose. This one device makes counting fun. Unlike traditional 100-bead abacuses, the beads are designed to be sharp and easy to handle. Also, even children who are not good with finger dexterity can develop a sense of numbers with the same feel as a 100-bead abacus. Three advantages for counting 10: (1) The sides of the beads are black, making them clearly visible. (2) Fingers can easily fit in, allowing for accurate bead movement. (3) Two units can be connected to create a 20-bead abacus. It also has a non-slip feature to prevent slipping. An easy-to-understand manual is included.
