Adding and subtracting decimals word problems

The topic  is a topic under the 6th Grade Math Mission. This exercise involves basic word problems to practice addition and subtraction operations on decimals.

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


 * 1) Adding word problem: This problem describes a situation that asks for a total amount or some other addition problem. The student is asked to find the correct sum and write it in the box.Aasdwp1.png
 * 2) Subtracting word problem: This problem describes a situation that involves a difference or other subtraction type problem. The student is asked to find the correct difference and write it in the box.Aasdwp2.png

Strategies
This exercise is easy to get accuracy and speed badges because the problem types repeat at a fairly fast rate, the same type of total and same type of difference. Also, the numbers were often easy to work with making it possible to do these without a calculator and thereby increase speed.
 * 1) When adding and subtracting decimals on paper, be sure to line up the decimal points.
 * 2) The numbers on the problems are not particular large and borrowing and carrying does not happen on every problem, read it first to see if you can answer without writing it out to increase speed.
 * 3) Phrases like "how much faster" and "total" can be used as predictors of the operation needed to perform the problem.
