Math Talk:

Have a conversation about this image. Be curious. Be creative. Can you see in different ways?

What shapes and angles do you notice? How do see this machine? How does it measure distance?

A drawing of Archemedes' odometer (circa 264-241 BC), to measure distance. What do you notice? How does it work? What can you imagine? How could this tool help measure area and perimeter?
