One-to-one correspondence in counting collections to 20
Coordinate one number word with each object exactly once when counting a collection. Touch, move, or mark each object as it is counted to prevent double-counting or skipping. Collections in line, in array, and (stretch) in scattered arrangement.

Common misconceptions
- Counts the same object twice when objects are arranged in a circle (loses starting position).
- Skips an object when objects are scattered and not moved.
- Says count-words faster than touching objects (word-object decoupling — Fuson's 'production deficiency').
- Touches multiple objects per word when collection is large and child is rushing.
