Measure from 0 each time. A centimeter is shorter than an inch, so it takes more of them to cover the same length: the smaller the unit, the bigger the number.
Watch for: Thinking the thing got longer because the number is bigger. Circling centimeter as the longer unit. Using the same side of the ruler for both measurements.
At home: Measure a book with paperclips and then with crayons. Ask why it took more paperclips.
