Equivalent fractions on the number line

The first instance of  is under the 3rd Grade Math Mission. This exercise explores the concept of different representations of fractions which is especially important as different representation of numbers with equal value is foundation to much of arithmetic.

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


 * 1) Move the dot a number of marks: This problem has the student move a point to the correct spot on a number line. After that, they ask how many of the denominations were needed to get to that point.Eqfr1.png
 * 2) Unreduce the fraction: This problem uses markings on a number line and asks the student to identify which unreduced fraction is the same value as a given reduced fraction.Eqfr2.png

Strategies
This exercise is easy to get accuracy badges with sufficient knowledge of fractions. It is also easy to get speed badges because the problem can be tabbed and entered easily.


 * 1) For the second type of problem, you can just reduce the fractions in the answer choices and find the one that is equivalent to the given fraction. No real need to wait for the picture although it helps to visualize where the fractions are located.
