Interpreting dot plots with fraction operations

The topic  is under the 5th Grade Math Mission. This exercise also works word problems, but also uses line plots and concentrates on working with fractions.

Types of Problems
There is one type of problem in this exercise:


 * 1) Use plot to solve problem: This problem provides a line plot modeling a situation. The student is asked to solve a problem and answer based on the information provided in the line plot.Lastmeas.png

Strategies
This exercise is medium to get accuracy badges because working with arithmetic on mixed numbers can provide a slight challenge. The speed badges are easy once you get into the correct rhythm.
 * 1) The problems seem to primarily be the difference between the top two and the difference between the top and bottom (range).
 * 2) The answer can be either a decimal or a fraction, so it seems easiest to give the answer as a decimal.
 * 3) Also! The decimal ticks marks so far seem to be terminating decimals. You can avoid having to deal with subtracting mixed numbers if you mentally change fourths, eighths, etc into decimals.
