			STANDARD			CCSS.Math.Content.K.CC.B.5	Count to answer ''how many?'' questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects. (materials correlated to this standard)

			STANDARD			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. (materials correlated to this standard)
			STANDARD			CCSS.Math.Content.K.CC.C.7	Compare two numbers between 1 and 10 presented as written numerals. (materials correlated to this standard)
	STRAND / DOMAIN						Operations and Algebraic Thinking

			STANDARD			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. (materials correlated to this standard)
			STANDARD			CCSS.Math.Content.K.OA.A.3	Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1). (materials correlated to this standard)
			STANDARD			CCSS.Math.Content.K.OA.A.4	For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation. (materials correlated to this standard)

	STRAND / DOMAIN						Number and Operations in Base Ten
		CATEGORY / CLUSTER				CCSS.Math.Content.K.NBT.A	Work with numbers 11-19 to gain foundations for place value.
			STANDARD			CCSS.Math.Content.K.NBT.A.1	Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
