I really like this post about giving a real reason to use ratios. Check it out: "Give them a recipe that involves two quantities, such as lemons and cups of sugar and ask them how to make more lemonade that tastes the same and less lemonade that tastes the same. Have them record different values in a labeled table.". See more examples of this train of thought. Thanks to Dan Meyer for this one.
