Walk a number down the metric staircase — each step is one ×10 and one decimal place — until it lands on the target unit.
The metric system is a staircase of tens: each step between km, m, cm, mm (or L–mL, kg–g) is one ×10 and one place for the decimal to move. The child walks the number the right number of steps to convert it. Making the ×10 ladder explicit turns metric conversion into counting steps. Best for Grades 4–6.
