FAQ

What makes metric conversions easier than customary conversions?

The metric system is base-10, so every conversion involves simply multiplying or dividing by 10, 100, or 1,000 — the same moves students already make when working with decimals.

What mnemonic helps students remember the metric length hierarchy?

Many teachers use 'King Henry Died By Drinking Chocolate Milk' (kilo-, hecto-, deka-, base, deci-, centi-, milli-) to help students recall the order of metric prefixes.

How do these worksheets connect to science class?

Science measurements almost always use metric units, so fluent mm/cm/m/km conversion is a prerequisite skill for 5th grade lab work and data recording.
