When trying to solve a worded problem use the following checklist;

2. Make a list of the numerical (number) information you’ll need. If the numbers have units

attached (for example, 10 metres), make sure you attach units in your list so you don’t get

confused.

3. Write out the number equation you’ll need to solve.

4. Complete the solving process carefully.

5. When you get your answer, reread the problem and ask yourself, “Does this answer make sense?”
