Abacus - 20 beads (2 rows)

Use this 20-bead abacus to help children build a solid number sense for the numbers 1-20. As it combines three math learning tools in one – counters, a number line, and the base of ten – it is ideal for incorporating into work schedules when children are learning to count, add, subtract, and subitize. Each row has 10 beads (5 red and 5 white) that give students a visual way to anchor numbers up to 5 and 10. The sturdy wooden rack is 23 cm long and is the ideal size for students to use at their desk.
