Imagine trying to launch a rocket ship, but you shout random words instead of counting! To make things work, we need our counting words to march in the exact right line.
The Counting Line
When we count, we always start with one and move forward step by step: one, two, three, four, five.
In 1978, scientists Rochel Gelman and Randy Gallistel discovered that all great counters follow the stable order principle—a rule that number words must never trade places or skip ahead.

Why Order Matters
Number words are like train cars connected in a row. If you say "one, three, two," the track breaks because two must always come right after one.

Can you use your own hand to practice the stable order?
Hand Counting
Start with a closed fist. Pop up your fingers one at a time and say each word aloud: one, two, three, four, five!
