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, etc. 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. -Gail, for the T2T service
