 * Grade:3 Unit:5 Week: 2 Content: Math Dates: 2/25-3/1 **


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


 * Essential Questions: **
 * Do I understand perimeter as the measure around the outside edges of a two-dimensional
 * figure?
 * How can I find the perimeter using standard units?
 * How can I create different shapes with the same perimeter?
 * How can I find the perimeter of an irregular shape?


 * 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 **
 * Create different shapes with the same perimeter.
 * Find perimeter using standard units.
 * Understand perimeter as the measure around the outside edges of two-dimensional figure.

Building a Dog Park Students (in pairs) will choose a dog that they will build a park for. This week students should determine how big of a yard is needed depending on the kind and size of their dog choice. (They may need to research this information.) They will determine how fencing is need to fence the perimeter of the park. Each pair will create a design sheet on grid paper. The dimensions for the fence should be clearly marked on the design sheet.

 * Key Questions (match Standard)
 * How accurately to students predict the order of the perimeters of the shapes from shortest to longest?
 * Do students accurately measure the perimeter of each shape?
 * Are students able to explain why their prediction of the order maybe different from the actual order of the shapes by perimeter?
 * Are students able to determine the missing measures from given information?
 * Do students accurately determine the perimeter of rectangles?


 * Observable Student Behaviors (Performance)
 * Student accurately predicts the order of the perimeters of the shapes from shortes
 * to longest.
 * Student accurately measures the perimeter of each shape.
 * Student is able to explain why their prediction of the order maybe different from the
 * actual order of the shapes by perimeter.
 * Student is able to determine the missing measure from given information.
 * Student accurately determines the perimeter of rectangles.


 * ** 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. ||
