= Topic 12: Measure Lengths = Pacing (Duration of Unit): 5 Lessons 1. Makes sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning. ||

 * __**Transfer:**__
 * __**Established Goals:**__
 * 1.MD.1 Order three objects by length; compare the lengths of two objects indirectly by using a third object.
 * 1.MD.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 with no gaps or overlaps.

__**Student "I Can" Statements:**__


 * I can put three objects in order from longest to shortest and compare their lengths.
 * I can tell the length of an object using whole numbers.
 * I can show that I understand how to measure something by using a smaller object as a measurement tool.

__**Prerequisite Standards:**__


 * 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. ||
 * **__Big Ideas:__**

Numbers, expressions, measures, and objects can be compared and related to other numbers, expressions, measures, and objects in different ways.
 * Comparison and Relationships **

Some attributes of objects are measurable and can be quantified using unit amounts.
 * Measurement**


 * Practices, Processes, and Proficiencies **

Mathematics content and practices can be applied to solve problems. || __**Essential Questions:**__


 * What are ways to measure how long an object is? ||
 * __**Students will know...**__


 * Objects can be compared and ordered by length.
 * Two objects can be compared indirectly by comparing both to a third object.
 * Measurement is a process of comparing a unit to the object being measured. The length of any object can be used as a measurement unit for length.
 * Measurement is a process of comparing a unit to the object being measured. The length of any object can be used as a measurement unit of length. Objects can be measured to compare and order their lengths and heights.
 * Mathematicians know how to pick the right tools to solve math problems.
