 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.



 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:

 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."
