Relate division to multiplication

The first instance of  is under the 3rd Grade Math Mission. This exercise explores strengthens the relationship between multiplication and division as inverse operations.

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


 * 1) Fill in the blank: This problem has three pairs of related multiplication and division questions. The student is to insert the missing number in all six equations.Relmd.png
 * 2) Answer the questions: This problem has four equations that are all related to each other. The student is to type the correct answer in a box or select the correct option from a drop-down menu on four problems.Relmd2.png

Strategies
This exercise is easy to get accuracy badges because the numbers are small. However, speed badges are hard to attain because there is more than one question to answer in each problem.


 * 1) On the first problem type, the answer for the first equation in a pair is the same as the answer to the second of the pair. The problem is supposed to stress the interrelatedness of multiplication and division after all.
 * 2) On the second type of problem a visual aid is sometimes (but not always) drawn.
 * 3) On the second type of problem, the first equation will tell you all three numbers that could possibly show up in any other problem. You can keep those three numbers in mind and fill in the other equations with the number that is missing from the triplet.
