K.NS.1

The student will utilize flexible counting strategies to determine and describe quantities up to 100.

K.NS.1.aUse one-to-one correspondence to determine how many are in a given set containing 30 or fewer concrete objects (e.g., cubes, pennies, balls), and describe the last number named as the total number of objects counted.K.NS.1.bRecognize and explain that the number of objects remains the same regardless of the arrangement or the order in which the objects are counted.K.NS.1.cRepresent forward counting by ones using a variety of tools, including five-frames, ten-frames, and number paths (a prelude to number lines).K.NS.1.dCount forward orally by ones from 0 to 100.K.NS.1.eCount forward orally by ones, within 100, starting at any given number.K.NS.1.fCount backward orally by ones when given any number between 1 and 20.K.NS.1.gState the number after, without counting, when given any number between 0 and 30.K.NS.1.hState the number before, without counting, when given any number between 1 and 20.K.NS.1.iUse objects, drawings, words, or numbers to compose and decompose numbers 11-19 into a ten and some ones.K.NS.1.jGroup a collection of up to 100 objects (e.g., counters, pennies, cubes) into sets of ten and count by tens to determine the total (e.g., there are 3 groups of ten and 6 leftovers, 36 total objects).
