Finding area by multiplying

The first instance of  is under the 3rd Grade Math Mission. This exercise tries to connect multiplication (and arithmetic concept) with area (a geometric concept) in a meaningful way.

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


 * 1) Realize multiply is area: This problem has an array of squares drawn. The student is to fill in three numbers and one pop-up menu to complete the problem.Aremult1.png
 * 2) Fill in information: This problem has an area problem illustrated as a multiplication problem. The student is tasked to fill in the five correct answers, including rows and columns twice and the answer for the area.Aremult2.png

Strategies
This exercise is medium to get accuracy badges because of the careful reading that is necessary to make sure you are comparing rows and columns correctly. This necessary careful reading makes speed badges hard.


 * 1) On the first problem type, the drop down solution is always multiply which is found by pressing down three times in the drop down menu.
 * 2) On the second problem type the order of the questions (width vs. length) can change in the second set of entries. This is very good as length and width can be viewed as somewhat ambiguous.
