K.CC.B.4 Connect counting to cardinality

Understand the relationship between numbers and quantities; connect counting to cardinality: a. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. b. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted. c. Understand that each successive number name refers to a quantity that is one larger.

Why water teaches this standard well

Students touch and count a set of blue water-drop counters or fish cutouts one at a time, learning that the last number they say names the whole group no matter how the drops are arranged. This one-to-one pairing is the foundation for every later tally of rain gauge readings or bottles collected.
