3. Answers and Visual Solution Prompts for Advanced Cube Conversations (Days 16-20)
The Answers to the Advanced Cube Conversations (Days 16-20) are found on these slides.
In addition, I’m sharing a sampling of my notes here so you can see a couple of the ways I’ve approached the solutions. I’m only posting enough of each solution pathway to show an example and to prompt discussion. You might find the images which are partially completed to be compelling visuals for discussion.
Remember that you can download the printable Cube Conversations Book from this page on my blog. The printable pages will provide your students with plenty of space to approach these tasks in a wide variety of ways. One your students write, they will have a rich opportunity to describe their math thinking to each other.
Enjoy the journey and feel free to share your learning experiences with others! You can find me on
