Hi Rico,
Have you considered giving students handful of pattern blocks, and then
having them write as many different ratios as they can using the set they
have pulled.  It is very important for students to think about not only part
- whole relationships, but also part - part relationships.  For example, they
may pull a handful of pieces that contains 4 squares, 3 trapezoids, and 5
parallelograms.  They could name

Squares to trapezoids, 
Squares to non- Squares
Squares to figures
Squares to parallelograms,

And don't forget all of the equivalent ratios that can be considered as 
well.  The more different ways students can look at a set of figures and 
describe it using ratios, the better their foundation will be later on, 
when they use ratios to explore proportional reasoning.
