 * Grade:3 Unit:5 Week: 1 Content: Math Dates: 2/19-22**


 * Theme Essential Question **** : How do find the perimeter and area of a polygon? **


 * Essential Questions: **
 * What units do I use to measure length?
 * How do I use benchmark measurements?
 * How do I use standard and meteric units of length to measure accurately?
 * How do I recognize and explain possible sources of measurement errors?
 * Do I understand the meaning of perimeter?
 * How do I find the perimeter of a polygon using standards units?


 * Standards **
 * 3.MD.8 ** Geometeric measurement: Recognize perimeter as an attribute of plane figures and distinguish between linear and area measures. Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different area or with the same area and different perimeter.


 * Objectives **
 * Review the length of units of measure. (inch, foot, yard, centimeter, meter)
 * Establish measurement benchmarks.
 * Understand perimeter as the measure around the outside edges of a 2-dimensional figure.
 * Find perimeter using standard units.
 * Use U.S. standard and meteric units to accurately measure length.
 * Recognize and explain possible sources of measurement error.

 * Key Questions (match Standard)
 * Are students using measurement tools accurately?
 * Are students making reasonable estimates for each unit of measure?
 * Do students choose appropriate tool for finding the perimeter?
 * Do students know to add up all the measurements of the sides to find the total
 * perimeter?
 * Do students measure each side of a rectangle or do they recognize that they need
 * to measure only one length and width?
 * Do students have strategies to measure the perimeter of objects with curved
 * sides?
 * Can students create multiple shapes from a given perimeter?


 * Observable Student Behaviors (Performance)
 * Student uses measurement tools accurately.
 * Student makes reasonable estimates for each unti of measure.
 * Student chooses appropriate tool finding the perimeter.
 * Student knows to add up all the measurements of the sides to find the total
 * perimeter.
 * Student recognizes to measure only one length and one width when finding the
 * perimeter of a rectangle.
 * Student has strategies to measure the perimeter of objects with curved sides.
 * Student is able to create multiple shapes from a given perimeter.


 * **Mathematical Practices **
 * Make sense of problems and persevere in
 * solving them.
 * Reason abstractly and quantitatively.
 * 3. Construct viable arguments and critique the reasoning of others.
 * Model with mathematics.
 * Use appropriate tools strategically.
 * Attend to precision.
 * Look for and make use of structure.
 * 8. Look for and express regularity in repeated reasoning. ||
