Hover over the cards to reveal the numbers
Look at each abacus representation and try to determine the number before hovering to reveal the answer. The abacus shows numbers using beads: each column represents a place value (ones, tens, hundreds, etc.). In each column, the top bead represents 5 and the bottom beads each represent 1.
Tip: You can print these cards for offline practice. Numbers will be faintly visible in print mode.
