Common Core State Standards
CCSS.Math.Content.K.CC Counting and Cardinality
CCSS.Math.Content.K.CC.A Know number names and the count sequence.
CCSS.Math.Content.K.CC.A.1 Count to 100 by ones and by tens.
CCSS.Math.Content.K.CC.A.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
CCSS.Math.Content.K.CC.B Count to tell the number of objects.
CCSS.Math.Content.K.CC.B.4 Understand the relationship between numbers and quantities; connect counting to cardinality.
CCSS.Math.Content.K.CC.B.4c Understand that each successive number name refers to a quantity that is one larger.
CCSS.Math.Content.K.CC.C Compare numbers.
CCSS.Math.Content.K.CC.C.6 Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies.
CCSS.Math.Content.K.OA Operations and Algebraic Thinking
CCSS.Math.Content.K.OA.A Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
CCSS.Math.Content.K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
CCSS.Math.Content.K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
CCSS.Math.Content.K.OA.A.5 Fluently add and subtract within 5.
