To make a simple abacus, you'll need a sturdy base, such as a wooden or cardboard board, and some rods or dowels to serve as the columns for the beads. Cut the rods to a uniform length and secure them vertically onto the base, ensuring they are evenly spaced. Use beads—typically two for the lower section and five for the upper section of each column—to represent numbers. Finally, thread the beads onto the rods, allowing them to slide freely for counting and calculations.
