VISUALIZATIONS FROM THE CENSUS BUREAU

https://www.census.gov/schools/activities/math.html

Among its math materials for teaching and learning with
real-life data, the U.S. Census Bureau provides
twenty visualizations.

A game called "Population Bracketology" presents 64 of the
nation's urban centers in the pair-wise format of a knock-out
tournament for students to pick the larger populations. Toggle
the radio button for "State Population" and then press the "New
Game" button for a similar challenge involving the fifty
states, the District of Columbia, Guam, the Commonwealth of the
Northern Mariana Islands, the U.S. Virgin Islands, and
American Samoa.

Other visualizations from the Bureau's program "Statistics in
Schools" include animations of population density
profiles along interstate highways I-5, I-90, and I-95; and
"Islands of High Income," which shows how median household
income varies by county.

Click "View Data Table" below any visualization for its raw
numbers. Some also come with a standards-aligned,
classroom-ready activity; keep scrolling down for more.

MORE FOR THE TOTAL SOLAR ECLIPSE

http://mathforum.org/electronic.newsletter/mf.intnews22.26.html

Even more resources have come to light since we first featured
the total eclipse that will cross the country on Monday,
August 21.

For starters, the Eclipse Megamovie Project has rolled out an
app to help viewers contribute to its citizen science effort.
Download Eclipse Megamovie Mobile, created by UC Berkeley
partner Ideum, and practice filtering the cameras of your
Android and Apple mobile devices ahead of the
event; respectively,

The American Astronomical Society (AAS) has collected some
educational videos and other materials:

https://eclipse.aas.org/resources/educational-materials

In particular, check out the free online course recommended by
the AAS. "The Sun and the Total Eclipse of August 2017" was
created by Douglas Duncan, an astronomer at the University of
Colorado. Describing its fifth and final unit, Duncan notes
that "weeks 1-4 give a lot of explanation of what you will see,
so I hope you take the full course, but if you are in a hurry,
this week alone will prepare you."
