Cardinality — the last number said names the total count (CCSS K.CC.B.4)
Understand that when counting objects, the last number named tells the total number of objects (cardinality principle). Re-count a collection from a different starting object and verify the total stays the same (order-irrelevance principle). Answer 'how many?' with a single numeral, not a recount.

Common misconceptions
- Recounts the collection when asked 'how many?' — treats the count-word sequence as a label not a total.
- Says a different number when asked 'how many?' (gives next number in sequence rather than last said).
- When set is re-ordered, counts again and accepts a different total (no order-irrelevance).
- When given a written numeral 7 and asked to make 7, makes 7 then keeps adding (no cardinal stopping rule).
