Thank you for your patience!<\/p>\n<p>I've had a very busy few months, especially now that I'm doing freelance training work. My many tasks have included:<\/p>\n<ul>\n<li>Training teachers (running courses and giving feedback on lesson videos) <\/li>\n<li>Training university math lecturers (mostly one-on-one feedback on lectures) <\/li>\n<li>Doing volunteer training in Cambodia (Phnom Penh and Battambang)<\/li>\n<li>Developing online mathematics courses<\/li>\n<\/ul>\n<p>I'm a bit more free over the next few months so I hope to get back to writing the Newsletter more often. I've got a large number of article requests and I'm looking forward to writing them! <\/p>\n<h2>2.

Resource: GeoGebra Examples <\/h2>\n<p>GeoGebra is an excellent free math exploration tool. (All schools should use it and give students interesting assignments where they learn math by making geometric constructions.) <\/p>\n<table border=\"0\" cellpadding=\"5\">\n<tbody>\n<tr>\n<td><a href=\"http:\/\/www.malinc.se\/math\/\"><img loading=\"lazy\" src=\"\/blog\/wp-content\/images\/2012\/10\/bezier-flower.gif\" alt=\"Bezier flower made with GeoGebra\" title=\"Bezier flower made with GeoGebra\" border=\"0\" height=\"100\" width=\"128\" \/><\/a><\/td>\n<td>\n<p>See <a href=\"http:\/\/www.malinc.se\/math\/\">several GeoGebra examples<\/a> by Malin Christersson.

Intmath polls<\/h2>\n<p>The  recent IntMath poll (August to October 2012) asked readers about their use of gadgets when learning math. We hear a lot about how tablets are taking over in this &quot;post-PC&quot; era, but not yet, based on this (very unscientific) set of results. It's interesting that the numbers of students using calculator and mobile phone are very close. With a good phone app, you don't really need a calculator. <\/p>\n<p><strong>I mostly learn math using:<\/strong><\/p>\n<p>Laptop: 25%<\/p>\n<p>No device: 24%<\/p>\n<p>Computer (desktop): 20%<\/p>\n<p>Calculator: 15%<\/p>\n<p>Mobile phone: 12%<\/p>\n<p>Tablet (iPad etc): 4%<\/p>\n<p>Total votes: <strong>3900<\/strong><\/p>\n<p><strong>Latest poll - math homework: <\/strong>The current poll asks readers about the amount of math homework they do per week.

Math puzzles<\/h2>\n<p>The  <a href=\"https:\/\/www.intmath.com\/blog\/letters\/intmath-newsletter-no-cost-math-books-math-in-art-manga-guide-review-7551#puzzle\">puzzle in the last IntMath Newsletter<\/a> involved a story about Percy, Quincy and Robby. The correct answer (that Quincy gets $345) was given by Shaun, Peter Hunter, Thomas A Buckley and Dineth. As Dineth said, the puzzle had a bit of a problem, since $10 was left over and it was not clear who should get it. <\/p>\n<p id=\"puzzle\"><strong>Latest puzzle: <\/strong>A tangent at <em>P<\/em> to the smaller of 2 concentric circles intersects the outer circle at<em> Q <\/em>and<em> R<\/em> as shown.
