Comparing area and perimeter

The first instance of  is under the 3rd Grade Math Mission. This exercise continues the practice of finding area and perimeter of rectangles and helps to explore how area is related to perimeter

Types of Problems
There are two types of problems in this exercise:


 * 1) Use the situation to compare: This is a word problem with two objects that are supposed to be compared in perimeter and area. There are two multiple choice parts and two drop-down menus on this problem type.Perandarea1.png
 * 2) Drag the rectangles: This problem has several rectangles and the student is to drag the rectangles to the correct category of boxes to the right.Perandarea2.png

Strategies
This exercise is easy to get accuracy badges because the problems are not difficult. The speed badges feel hard at this time because of time limits, many questions asked, and load times for the pictures.


 * 1) In general for comparison, you do not need the full perimeter but can  instead use the semiperimeter by adding just two adjacent sides. It is faster for comparison problems.
 * 2) On the first problem type one of the measurements (either area or perimeter) will be the same and the other will not be.
 * 3) On the second problem type research did not see a problem where a rectangle did not belong in some box (although it might just be that not enough problems were checked).
