                   Summer Problems of the Week

                   SUMMER PROBLEMS OF THE WEEK


 This past Monday, we posted the last of our Current Problems
 of the Week (PoWs) for the 2016–2017 academic year. Each of
 these 120 challenging open-response math problems comes with
 its own supporting resources -- a treasure trove for designing
 your own summer projects.

 While we get ready for another series of PoWs starting mid
 August, we'll scale back our responses. But every two weeks
 from now until then, the Math Forum will continue to post PoWs
 and accept solutions.

 Want to get in on the fun, but don't have an account yet? A
 Current PoW membership provides access to this academic year's
 complete set, as well as the summer PoWs, plus all the puzzles
 coming next year -- quite a bargain for upward of 275 PoWs,
 their teacher packets, rubrics, and other supporting resources!



    Now taking place: Math education conversation of the day

 "This is awesome, I don't remember ever learning this in Lin.
 Algebra. I've googled this exact problem many times whenever it
 comes up, and this is the first time I've found an answer I'm
 really happy with that I can keep using. Thanks for sharing!"

 On Monday, Dan Meyer shared a tool that he uses to make the
 Math Twitterblogosphere (MTBoS) friendlier for newcomers.

 Meyer has observed that, for many, the "first leap into this
 teaching community was scary, that getting 'shot down' was bad,
 but bad also was simply getting ignored." So he hired a
 freelancer to build Tweets Highlighter -- an extension for the
 Chrome browser that identifies MTBoS-tagged tweets by math
 teachers who have tweeted fewer than 100 times:

uploads/ The Chief Academic Officer of Desmos has since written up the seven short steps it takes to install the extension: He invites others to join him aboard the MTBoS welcome wagon that reaches out to the online community's neophytes, and "make someone's day." -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- Now taking place: Math education conversation of the day "We need to stagger times b/c these chats rock the math world.

The original TV show debuted in 1968 and aired on the Public Broadcasting Service (PBS) for decades. The Fred Rogers Company maintains selections, such as video clips on science, technology, engineering, the arts & math (STEAM): But the online marathon, streaming through next Saturday on the social video platform Twitch, features the most comprehensive collection of episodes available. Many of the 886 shows have only aired once and are unavailable elsewhere online. Eleven days after the "Mister Rogers' Neighborhood" marathon wraps up, PBS will start its summer slate of professional development opportunities for math teachers, with such online courses as-- - Enabling Students with Special Needs to Succeed in Math Class - Encouraging Mathematical Communication Skills - Fostering Mathematical Reasoning Skills - The Evolution of Probability, Geometry, and Game Theory - Understanding Numbers and Operations: Addition and Subtraction in Grades PreK-3 Most offer opportunities to earn graduate credits from institutions that partner with PBS; and many districts allow teachers to apply these PBS TeacherLine courses towards continuing education units (CEUs) and professional development points (PDPs). Now through Wednesday, May 31, check out of the enrollment process with the promo code PBS+MATH to save 30% off of TeacherLine's newest course, "Differentiating Math Lessons for a Range of Learners": -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum at NCTM Online PD Online Workshops Ask Dr. Math Problems of the Week Powerful Problem Solving Mathematics Library Math Tools Teacher2Teacher Discussion Groups Join the Math Forum Ask Dr. Math Books Facebook Blogs Twitter Feed SEND COMMENTS TO: _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
