The  exercise appears under the 6th grade (U.S.) Math Mission. This exercise practices ordering rational numbers.

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


 * 1) Order the following numbers: This problem gives the user a set of numbers. The user is asked to order these numbers from least to greatest by dragging the numbers around. Ordering.png

Strategies

 * 1) These problems become easy to solve if you make all the numbers one form, preferably decimals, because ordering decimals is easy.
 * 2) It is important to remember the negative sign in front of a number. Remember that ordering negative decimals is the reverse of ordering positive decimals.

Real-life Applications

 * Rational numbers are fractions (often percents)
 * Taxes are a fraction of the income or the purchase amount, so if you spend or earn money, you're involved with fractions.
 * If you share a pizza or a bag of popcorn, you each get a fraction of it.
 * Interest rates on loans, mortgages, and saving accounts are fractions.
 * If you watch TV, the picture has a constant 4/3 width to height ratio.
 * If you listen to music, the tones are in simple fraction relationships (3rds, 5ths, and so on).
 * If you use a flush toilet, the plumber had to know to make the slope of the waste line a basic fraction, 1/4 inch per foot (too steep, the liquid runs out from under the solids and the line clogs up)
 * If you ride a bike or drive a car, the gear ratios help you accelerate and climb and cruise.
