*Counting and Cardinality K.CC


Know number names and the count sequence.
K.CC.1 Count to 100 by ones and by tens.
K.CC.2 Count forward beginning from a given umber within the known sequence.
K.CC.3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 020.


Count to tell the number of objects.
K.CC.4 Understand the relationship between numbers and quantities; connect counting to cardinality.
K.CC.4a When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
K.CC.4b Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
K.CC.4c Understand tat each successive number name refers to a quantity that is one larger.
K.CC.5 Count to answer “how many?”


Compare Numbers.
K.CC.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,
K.CC.7 Compare two numbers between 1 and 10 presented as written numerals.


*Operations and Algebraic Thinking K.OA


Understand addition is putting together and adding to, and understand subtraction as taking apart and taking from.
K.OA.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, or verbal explanations, expressions, or equations.
K.OA.2 Solve addition and subtraction word problems, and add and subtract within 10.
K.OA.3 Decompose numbers less than or equal to 10 into pairs in more than one way,
K.OA.4 For any number from 1to 9, find the number that makes 10 when added to the given number.
K.OA.5 Fluently add and subtract within 5.


*Number and Operations in Base Ten K.NBT


Work with numbers 1119 to gain foundations for place value.
K.NBT.1 Compose and decompose numbers from 11to19 into ten ones and some further ones.


*Measurement and Data K.MD


Describe and compare measurable attributes.
K.MD.1 Describe measurable attributes of objects, such as length or weight.
K.MD.2 Directly compare two objects with a measurable attribute in common, to see which object has “more of”/”less of” the attribute, and describe the difference.


Classify objects and count the number of objects in each category.
K.MD.3 Classify objects into given categories; count the number s of objects in each category and sort the categories by count.


*Geometry K.G


Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).
K.G.1 Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.
K.G.2. Correctly name shapes regardless of their orientations or overall size.
K.G.3 Identify shapes as twodimensional (lying in a plane, “flat”) or threedimensional (“solid”).


Analyze, compare, create, and compose shapes.
K.G.4 Analyze and compare two and threedimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts .
K.G.5 Model shapes in the world by building shapes from components.
K.G.6 Compose simple shapes to form larger shapes.
