FAQ

Why should 1st graders learn to measure in centimeters?

Centimeters are the standard unit of length in most countries and in the sciences, so familiarity with the metric system from an early age builds scientific and global literacy.

How does measuring in centimeters compare in difficulty to measuring in inches?

The process is identical — align, read, identify nearest whole unit — but centimeters are smaller units, which means objects will have larger numeric measurements than in inches.

Do 1st graders need to convert between centimeters and inches?

No — conversion between metric and customary units is a 4th or 5th grade skill; at 1st grade, students simply practice using each unit independently.
