Use the Answers to Your Advantage
If your child is stumped by a multiple-choice question, use the answers to his advantage. Example: "What value of x satisfies the equation 4x + 2 =22?" If the answer choices are A. 3, B. 5, C. 7 and D. 9, he can estimate that A is too low and D is too high right away. Then, all he'll need to do is plug in answer choices B and C to see which works.
