**11**-**20**of**734**Standards#### Standard Identifier: K.G.2

Grade:

**K**
Domain:

**Geometry****Cluster**:

Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).

**Standard**:

Correctly name shapes regardless of their orientations or overall size.

#### Standard Identifier: K.G.3

Grade:

**K**
Domain:

**Geometry****Cluster**:

Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).

**Standard**:

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

#### Standard Identifier: K.G.4

Grade:

**K**
Domain:

**Geometry****Cluster**:

Analyze, compare, create, and compose shapes.

**Standard**:

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).

#### Standard Identifier: K.G.5

Grade:

**K**
Domain:

**Geometry****Cluster**:

Analyze, compare, create, and compose shapes.

**Standard**:

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

#### Standard Identifier: K.G.6

Grade:

**K**
Domain:

**Geometry****Cluster**:

Analyze, compare, create, and compose shapes.

**Standard**:

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

#### Standard Identifier: K.MD.1

Grade:

**K**
Domain:

**Measurement and Data****Cluster**:

Describe and compare measurable attributes.

**Standard**:

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

#### Standard Identifier: K.MD.2

Grade:

**K**
Domain:

**Measurement and Data****Cluster**:

Describe and compare measurable attributes.

**Standard**:

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.

#### Standard Identifier: K.MD.3

Grade:

**K**
Domain:

**Measurement and Data****Cluster**:

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

**Standard**:

Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.

**Footnote**:

Limit category counts to be less than or equal to 10.

#### Standard Identifier: K.NBT.1

Grade:

**K**
Domain:

**Number and Operations in Base Ten****Cluster**:

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

**Standard**:

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 (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

#### Standard Identifier: K.OA.1

Grade:

**K**
Domain:

**Operations and Algebraic Thinking****Cluster**:

Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.

**Standard**:

Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

**Footnote**:

Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)
