Converting units (metrics)

The topic  is under the 5th Grade Math Mission. This exercise practices familiarity with converting among and understanding different units of measurements.

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


 * 1) Convert in USCS: This problems provides a conversion question from one unit to another in the United States Customary System. The student is asked to find the correct answer to the conversion problem and write it in the available spot.ConunitUS.png
 * 2) Convert in metric: This problems provides a conversion question from one unit to another in the Metric System. The student is asked to find the correct answer to the conversion problem and write it in the available spot.ConunitMET.png
 * 3) Convert in time: This problems provides a conversion question from one unit to another in hours, minutes and seconds. The student is asked to find the correct answer to the conversion problem and write it in the available spot.ConunitTIM.png
 * 4) Fill in chart: This problem provides a chart with multiple conversion problems between two given units in the same system. The students is asked to fill in the chart correctly.ConunitTAB.png
 * 5) Put in order: This problem has several measurements possibly in different units in the same measurement system. The student is asked to put the amounts in increasing order.ConunitORDER.png

Strategies
This exercise is medium to get accuracy badges because the student needs to be careful about the units are getting smaller or larger. The speed badges are medium because there are so many different types of problems, making it difficult to get into a smooth rhythm.
 * 1) Moving in the metric system is as easy as moving the decimal place.
 * 2) The USCS system could be made easier by having a reference table at quick access.
