**1**-**10**of**131**Standards#### 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: 1.MD.1

Grade:

**1**
Domain:

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

Measure lengths indirectly and by iterating length units.

**Standard**:

Order three objects by length; compare the lengths of two objects indirectly by using a third object.

#### Standard Identifier: 1.MD.2

Grade:

**1**
Domain:

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

Measure lengths indirectly and by iterating length units.

**Standard**:

Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.

#### Standard Identifier: 1.MD.3

Grade:

**1**
Domain:

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

Tell and write time.

**Standard**:

Tell and write time in hours and half-hours using analog and digital clocks.

#### Standard Identifier: 1.MD.4

Grade:

**1**
Domain:

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

Represent and interpret data.

**Standard**:

Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

#### Standard Identifier: 2.MD.1

Grade:

**2**
Domain:

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

Measure and estimate lengths in standard units.

**Standard**:

Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.

#### Standard Identifier: 2.MD.10

Grade:

**2**
Domain:

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

Represent and interpret data.

**Standard**:

Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems4 using information presented in a bar graph.

**Footnote**:

See Glossary, Table 1.

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

Grade:

**2**
Domain:

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

Measure and estimate lengths in standard units.

**Standard**:

Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
