3.MD.8. 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 areas or with the same area and different perimeters. || ===‍‍‍‍‍‍**Anchor Standard/Mathematical Practice(s)**=== 1. Make 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 || Can the student justify a decision or course of action or make judgments based on a criteria or a standard? (checking, hypothesizing, critiquing, experimenting, and judging.) ||

3.MD.1 I can solve real world mathematical problems with perimeter.

 * Explain the relationship between polygons’ sides and their perimeter.
 * Explore perimeter in real life by walking around the sides of a room, using geoboards, tracing shapes on interactive whiteboards.
 * Measure and determine the perimeter of polygons to solve real world problems.
 * Solve problems by building multiple polygons for a given perimeter.
 * Determine which rectangle will have the greatest area when working with several rectangles that possess the same perimeter.
 * Compare figures with the same perimeter - different area and different perimeter – same area.
 * Change side length of a plane figure to observe changes in perimeter and area.
 * <span style="font-family: Arial,sans-serif; font-size: 10pt;">Use knowledge of factors and area to determine possible side lengths (unknown side)
 * <span style="font-family: Arial,sans-serif; font-size: 10pt;">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 areas or with the same area and different perimeters.
