Number Sense & Counting
Understanding quantities, counting with meaning, and recognizing written numerals.
Examples & Achievements
- Rote counts to 20 or beyond
- Counts objects with one-to-one correspondence up to 10-20
- Understands that the last number counted tells "how many" (cardinality)
- Recognizes written numerals 0-10
- Subitizes (instantly recognizes) small quantities (1-5) without counting
- Compares groups and tells which has more, fewer, or the same
How to Measure
- Accurately counts a set of 15 objects with one-to-one correspondence
- Names written numerals 0-10
- Answers "how many?" correctly after counting (demonstrates cardinality)
- Subitizes quantities of 1-4 on dot cards without counting
- Correctly compares two groups (more/fewer) for sets up to 10
