Code Description
MA.K.NSO.2.1: Recite the number names to 100 by ones and by tens. Starting at a given number, count forward within 100 and backward within 20.
Clarifications:
Clarification 1: When counting forward by ones, students are to say the number names in the standard order and understand that each successive number refers to a quantity that is one larger. When counting backward, students are to understand that each succeeding number in the count sequence refers to a quantity that is one less.

Clarification 2: Within this benchmark, the expectation is to recognize and count to 100 by the end of Kindergarten.

MA.K.NSO.2.2: Represent whole numbers from 10 to 20, using a unit of ten and a group of ones, with objects, drawings and expressions or equations.
MA.K.NSO.2.3: Locate, order and compare numbers from 0 to 20 using the number line and terms less than, equal to or greater than.
Clarifications:
Clarification 1: Within this benchmark, the expectation is not to use the relational symbols =,> or <.
Clarification 2: When comparing numbers from 0 to 20, both numbers are plotted on the same number line. 
Clarification 3: When locating numbers on the number line, the expectation includes filling in a missing number by counting from left to right on the number line.

How many MORE ones than ten?:

Students will review the procedure for using a ten-frame. Students will be introduced to the important foundational concept for place value that numbers 10-20 can be represented as a unit of tens and a group of ones. Students will practice subitizing skills (the ability to "instantly see how many") using a ten-frame and counters.

Working with Teen Numbers:

This lesson uses manipulatives, drawings, expressions and equations to provide understanding of the composition of teen numbers as a unit of ten and a group of ones.
