A square and a diamond. The times of 6:46 and 12:46 on an analog clockface. Within each pair, what's different? What's the same? A website that juxtaposes such pairs launched Tuesday. With "Same But Different," creator Sue Looney aims to call attention to how two things can share commonalities and how they can differ. Categories include-- - early numeracy; - addition/subtraction; - multiplication/division; - measurement; - place value; - fractions, ratios; - geometry; and - algebra. Looney provides a six-step instructional routine for "Same But Different." Click her new site's "About" tab and then "How to Use" for more on the number talk that she recommends, along with talk moves by teachers to keep the dialogue going among and between students. https://www.samebutdifferentmath.com/how-to-use/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- THE TRUE SIZE OF ... https://thetruesize.com/ Curious to compare even more in your world? The website "The True Size Of ..." makes relating U.S. states, provinces, and whole countries as easy as clicking and dragging. To put the Mercator projection into perspective, just search for place names, then drag their outlines around to compare the actual areas of the land masses. One of the co-creators of thetruesize.com made an interactive site to explore the differences in opportunity and access to resources afforded to different populations within U.S. society. The Social Inequality website builds bar graphs from your searches for American states, counties, and cities to compare different demographic groups' population sizes, median household incomes, and levels of education: http://www.socialinequality.co/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- STATISTIC OF THE YEAR http://www.rss.org.uk/statoftheyear What statistic best captures the year of 2017? In the spirit of Oxford English Dictionary's "Word of the Year" competition, the Royal Statistical Society seeks nominations for this year's most striking statistic. Since 1834, the society has served as the professional body for statisticians and data analysts the world over. Its web page lists examples and criteria for this new competition, and links to the downloadable nomination form: http://www.rss.org.uk/Images/PDF/get-involved/ NominationForm2017.docx Follow the fun on Twitter with the hashtag #statoftheyear: https://twitter.com/search?f=tweets&vertical=default&q=%23 StatoftheYear&src=typd Nominate your statistic by Thursday, November 23, which is Thanksgiving Day in the United States. Nominated statistics do not necessarily need to have been produced within 2017, but ideally have become relevant to the public interest this year. This newsletter has highlighted several sources of timely statistics such as the above-mentioned socialinequality.co. Another example is the "Significant Digits" feature from FiveThirtyEight. Every weekday since it launched three years ago, the "data journalism site" has posted this daily digest of "the telling numbers tucked inside the news": https://fivethirtyeight.com/tag/significant-digits/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum at NCTM http://mathforum.org/ Online PD http://mathforum.org/pd/ Online Workshops http://mathforum.org/workshops/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pows/ Powerful Problem Solving http://mathforum.org/pps/ Mathematics Library http://mathforum.org/library/ Math Tools http://mathforum.org/mathtools/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/kb/ Join the Math Forum http://mathforum.org/join.forum.html Ask Dr. Math Books http://mathforum.org/pubs/dr.mathbooks.html Facebook https://www.facebook.com/themathforumatnctm/ Blogs http://mathforum.org/blogs/pows/ Twitter Feed http://mathforum.org/pd/twitter.html SEND COMMENTS TO: http://mathforum.org/electronic.newsletter/mfin.faq.html#feedback _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ An archive of all the Math Forum newsletters and directions for subscribing can be found at http://mathforum.org/electronic.newsletter/ ```
