It is great to see how the sharing of ideas sparks new ideas. In 2011 Lyon and Bragg wrote an APMC article on the mathematics of kitchen gardens.

The authors highlight different types of proportion problems and how the authentic context of a kitchen garden may be used to spark interest in reasoning.
