Remember… These are READING math problems.. Take your time. Read the questions carefully. Underline, circle, and highlight the important parts of the word problem. Read all possible multiple choice answers before choosing your final answer. After you choose your answer, go back and re- read the question to make sure you answered what they were asking.
