Students in U.S. high schools can get free digital access to The New York Times until Sept. 1, 2021.
These maps show the growing zones (also called hardiness zones) for two time periods — one historical and one projected. The zones are based on the coldest temperature of the year at each location averaged over a 30-year period. Farmers and home gardeners use the zones on these maps to inform them of which plants will succeed in their area.
After looking closely at the maps above (or at this full-size image), answer these four questions:
What do you notice?
What do you wonder?
The questions are intended to build on one another, so try to answer them in order.
2. Next, join the conversation online by clicking on the comment button and posting in the box. (Teachers of students younger than 13 are welcome to post their students’ responses.)
3. Below the response box, there is an option for students to click on “Email me when my comment is published.” This sends the link to their response which they can share with their teacher.
4. After you have posted, read what others have said, then respond to someone else by posting a comment. Use the “Reply” button to address that student directly.
On Wednesday, April 7, teachers from our collaborator, the American Statistical Association, will facilitate this discussion from 9 a.m. to 2 p.m. Eastern time.
5. By Friday morning, April 9, we will reveal more information about the maps, including a free link to the article that included this graph, at the bottom of this post. We encourage you to post additional comments based on the article, possibly using statistical terms defined in the Stat Nuggets.
We’ll post more information here on Thursday afternoon. Stay tuned!

• Go to the American Statistical Association K-12 website, which includes teacher statistics resources, professional development opportunities, and more.
Students 13 and older in the United States and the United Kingdom, and 16 and older elsewhere, are invited to comment. All comments are moderated by the Learning Network staff, but please keep in mind that once your comment is accepted, it will be made public.
