When I throw Ruby a treat, she follows it through the air and moves to catch it. A small, everyday moment that raises an unexpected question: do dogs know mathematics?
Ruby does not know what a parabola is or solve quadratic equations. Yet she responds to movement, distance and direction. The treat follows a trajectory mathematics can describe. The curve in the film illustrates that idea, rather than measuring the actual throw.

Read the film transcriptA successful catch does not mean Ruby is doing formal mathematics. But it invites us to think about the difference between experiencing a relationship and knowing the language used to describe it.
For a teacher, that distinction matters. Students may notice patterns, estimate distances or compare quantities before they can express them in symbols. Teaching can begin with those experiences and help connect them to drawings, mathematical language and reasoning.
There is mathematics in everyone. Sometimes, we just need to know how to bring it out.
