How to outline a simple math word problem? Here are some steps that you can follow to outline a simple math problem: Read the entire problem at least 3 times. Take a quick scan on your very first attempt, and then the remaining two will be very slow so that you can gather important information hidden within the question. Try to make a pictorial representation of the problem. It will make the information more sensible and real to you. Use the information that you have gathered to make a table where the blank portions indicate all the information which is still unknown. Assign some kind of variable or letter for all the unknown data. It will allow you to make an equation. Translate the English terms in the form of a mathematical equation. It is one of the main issues in word problems that the problem is not expressed in a mathematical equation. Check if the equation you made makes any sense and is the equation using all the information mentioned. Use mathematic rules to solve the equation. Check your answer(s) to see if they make sense according to what information was provided. Cross-check your answers by using the answer in place of the information that was previously unknown. These worksheets have students compleet problems that undergo an addition or subtraction operation. This is a an algebra primer.
