Homework for Thursday, 12/7

Assignment:  Subtracting Negatives #1 (differentiated)
*The lesson today was that it is much easier to add than to subtract.  While it seems like extra work at this time to change everything into an addition problem, it will help you to think about it this way in the future.
-Remember:  we have good cowboys and bad cowboys. 
-Remember:  subtracting a negative number is really just cowboys undercover: bad cowboys that are really good!  5 - (-3) = 5 + 3
-Remember:  rules might confuse you: do not count negative signs, don't worry about subtracting, just collect your cowboys.  Who wins?  That's your answer.
*You will find a more thorough description of subtracting negatives on the Mo'Help page of this blog.
*You will find plenty of practice problems on my Quizlet page. 
Due Thursday
