Perceptual and Conceptual Subitizing to 10

Instantly recognize small quantities up to 5 and compose larger quantities up to 10 using dot cards, five-frames, and ten-frames without counting one by one.

Count, quantify, and construct collections of up to 20 objects in diverse arrangements using one-to-one correspondence, cardinality, conservation, and hierarchical inclusion.

Read, write, and represent numerals 0 through 20 with physical manipulatives, drawings, zero as empty sets, and positions on a number line.

Recite forward oral counting sequences by ones and tens up to 100, count backward from 20 to 0, and count forward from any starting number.

Compare sets of objects up to 20 and numerals 1 to 10 using one-to-one matching, counting strategies, and comparative language.

Skip count forward by 2s to 20, and by 5s and 10s to 100, connecting skip counting patterns to paired items, nickel/dime coin values, and bundle groups.
