Subtraction word problems within 10

The first instance of the Subtraction word problems within 10 exercise is under the Early Math Math Mission. This exercise puts subtracting into a context and has students understand not just the arithmetic operation but also how it applies to situations.

Types of problems
There are three types of problems that show up in this exercise:
 * 1) Select total picture: This problem describes a subtraction problem in a context. The solution is one of the pictures that the student can select.Subwp-1.png
 * 2) Enter the difference: This problem has a situation and the answer is a number which the student is to type into the answer box.Subwp-3.png
 * 3) Select and enter: This problem has a multiple choice selection AND a fill in the blank part for the student to complete.Subwp-4.png

Strategies
The numbers are small on these problems so although there are many different types of problems the accuracy and speed badges can be done fairly easily.


 * 1) Since these problems are certainly subtraction, you can perform the subtraction operation as soon as you see the numbers instead of reading the complete problem. This will not work on problems that combine adding and subtracting.
