## Grade K - Measurement and Data

 Subject: Mathematics (NYS P-12 Common Core)
 Unit Title: Grade K - Measurement and Data
 Approx. Number of Weeks: March

#### Unit Summary:

Attributes of objects, such as length and weight, can be measured.

Solve problems by using measurable attributes and comparing objects according to length and weight.

 Collaboration & Communication Creativity & Innovation Critical Thinking & Problem Solving Research & Information Fluency Social & Emotional Intelligence

### 1. What will students know and be able to do?

#### Standards:

 K.MD.1 - Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. 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. For example, directly compare the heights of two children and describe one child as taller/shorter. K.MD.3 - Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.3

#### Essential Understandings:

Students will understand that…

Objects have attributes that can be measured.

#### Essential Questions:

Why do we measure?

Possible ways to scaffold the question:

• What can we measure? (attributes)
• How can we use what we measure to compare?

Possible ways to scaffold the question:

• Why do we measure?
• What attributes of an object can be measured?
• Does how I measure matter?

#### Students will know:

Objects can be described for their measureable attributes such as length and weight.

Two objects, with a common measurable attribute, can be compared as to which has more or less of that attribute and the difference can be described.

Objects can be classified into given categories, counted and sorted.

#### Students will be able to:

Measurement and Data

Describe and compare measurable attributes.

• Describe measurable attributes of objects, such as length or weight. (K.MD.!)

Describe several measurable attributes of a single object.

• 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. (K.MD.2)

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.

• Classify objects into given categories; count the numbers of objects in each category and sort the categories by count. (K.MD.3)
