 * Grade:3 Unit:5 Week: 4 Content: Math Dates: 3/11-3/14 **


 * Theme Essential Question **** : What is a polygon and how can I find the perimeter and area of that polygon? (Rectangles) **


 * Essential Questions: **
 * How can I find the area of a partial covered rectangle?
 * How can I find the area of irregular shape?
 * How do I design the shape for a given area?
 * How do I find the area by counting or calculating whole and partial square units?


 * Standards **
 * 3.MD.5a ** Geometric Measurement: Understand concepts of area and relate area to multiplication and addition. Recognize area has an attribute of plane figures and understand concepts of area measurement. A square with side length 1 unit, called “a square units,” is said to have “one square unit” of area, and can be used to measure area.


 * 3.MD.5b ** Geometric Measurement: Understand concepts of area and relate area to multiplication and addition. Recognize area has an attribute of plane figures and understand concepts of area measurement. A plane figure which can be covered without gaps or overlaps by n unit squares is said to have an area of n square units.


 * 3.MD.6 ** Geometric Measurement: Understand concepts of area and relate area to multiplication and to addition. Measure areas by counting unit squares (square centimeter, square meter, square inch, square ft, and improvised units).


 * 3.MD.7a ** Find the area of a rectangle with whole number size by tiling it, and show that the area is the same as would be found by multiplying the side lengths.


 * 3.MD.7b ** Multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real world and mathematical problems, and represent whole number products as rectangular areas in mathematical reasoning.


 * 3.MD.7d ** Recognize as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts applying this technique to solve real world problems.


 * Objectives **
 * Find the area of partially covered rectangles.
 * Find the area of an irregular shape.
 * Find the perimeter of an irregular shape.
 * Design a shape for a given area.
 * Find the area by counting or calculating whole and partial square units.

This week students will finish their Dog Park project by calculating the cost of the fencing and sod. This can be done by using online resources or by sales paper. Total cost of the project should be explained on their design sheet.
 * Assessment **
 * Product


 * Key Questions (match Standard)
 * Do students know which measurement is area and which one is perimeter?
 * How do students determine the perimeter and how do students determine the area?
 * How do students record their measurements? (correct labels)
 * Do accurately create shapes with a given area?
 * How do students explain how they determined the area?


 * Observable Student Behaviors (Performance)
 * Student knows which measurement is area an which one is perimeter.
 * Student determines the perimeter and area.
 * Student records their measurements using the correct labels.
 * Student is able to explain how they determine the area.


 * ** Mathematical Practices **
 * Make sense of problems and persevere in
 * solving them.
 * Reason abstractly and quantitatively.
 * 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. ||
