How many different combinations of people and dogs could walk by?

A dog walker goes by our building every day. They walk different numbers of dogs. Sometimes other people go with them, too. If 14 feet walk by, how many dogs and people could there be? What about 22 feet?

How could you get started?
• Think about 14 feet total. How many dogs could there be?
• How many feet do dogs usually have? How many feet do people usually have?
• Is your solution the only solution? How can you be sure?
• If you were to remove a dog from your solution, how many people could you add?
• What other numbers between 14 and 22  would make sense for this problem? What do you notice about the numbers that work?
• Are there any situations when the number of feet would be odd?
• Can you write a problem like this of your own?
