#### 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/sho...

#### CCSS.MATH.CONTENT.1.MD.A.1

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

#### CCSS.MATH.CONTENT.1.MD.A.2

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 wi...

#### Math K.7(A)

Give an example of a measurable attribute of a given object, including length, capacity, and weight; and

#### Math K.7(B)

Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

#### Math 1.7(A)

Use measuring tools to measure the length of objects to reinforce the continuous nature of linear measurement;

#### Math 1.7(B)

Illustrate that the length of an object is the number of same-size units of length that, when laid end-to-end with no gaps or overlaps, reach from one end of the object to the other;

#### Math 1.7(C)

Measure the same object/distance with units of two different lengths and describe how and why the measurements differ;

#### Math 1.7(D)

Describe a length to the nearest whole unit using a number and a unit; and
