April 26, 2013   |   Filed Under Common Core State Standards: Mathematics   |   Comments Off on Common Core State Standards for Kindergarten: Number and Operations in Base Ten

Work with numbers 11-19 to gain foundations for place value.

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.

Identify and describe shapes.

CCSS.Math.Content.K.G.A.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.

CCSS.Math.Content.K.G.A.2

Correctly name shapes regardless of their orientations or overall size.

CCSS.Math.Content.K.G.A.3

Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).

Analyze, compare, create, and compose shapes.

CCSS.Math.Content.K.G.B.4

Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/“corners”) and other attributes (e.g., having sides of equal length).

CCSS.Math.Content.K.G.B.5

Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

CCSS.Math.Content.K.G.B.6

Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”

Common Core State Standards for Kindergarten: Measurement and Data

Describe and compare measurable attributes.

CCSS.Math.Content.K.MD.A.1 

Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.

CCSS.Math.Content.K.MD.A.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. For example, directly compare the heights of two children and describe one child as taller/shorter.

Classify objects and count the number of objects in each category.

CCSS.Math.Content.K.MD.B.3 

Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.1
1 Limit category counts to be less than or equal to 10.
