Okay, so we know that using rich investigations in math, where learners have opportunities to experience ideas leads to richer, deeper understanding of those ideas (see article, p.1 Full Contact Math... more about mangoes).

Now... how do we recognize a good investigation/problem when we see one? How can we design quality investigations ourselves? How can we use what we see and hear in our classrooms to guide our problem-solving experiences? How can we use investigations to differentiate instruction?

Thoughtful answers to these and other questions can be found in this NCTM Publication, a compilation of insights by accomplished mathematics educators and researchers.

This book has its place on our ‘A’ shelf, the home of top-level resources we refer to repeatedly.
