    Notice that it takes grams of sugar to create cookies. Divide by to get the unit rate.

    Unit rate: grams of sugar per cookie

  3. To help him know how much sugar to use when baking cookies, Mr. Wallis started to make a table, as shown above. Copy and complete his table on your paper. 

    Proportions, again, will be very useful. A sample proportion is provided below.
