Turning a Word Problem Into a Function Table

[Anonymous]

Begin by identifying the changing quantity that will be your input. Give it a letter and a unit. Then identify the quantity you must find and label it as the output. Read the problem for a relationship such as a fixed fee plus a charge per item, a constant speed, or a repeated pattern. Translate that relationship into a rule before filling the table. Choose sensible input values, including zero when the context allows it, and calculate the outputs one row at a time. Keep units beside each number so you can catch mismatches. Check the first and last rows by substituting them back into the rule. If the question asks for a prediction, make sure the chosen input lies within a reasonable range. Finally, write a sentence that interprets the result in the context of the problem. This process turns a dense paragraph into organized, test ready information.
