16 December 2002 Vol. 7, No. 50 THE MATH FORUM INTERNET NEWS Pythagorgrams | BasketMath Interactive NRICH Maths, The Online Maths Club PYTHAGORGRAMS - June Lester http://thejuniverse.org/Mathdesign/widgets/Pythagoras/ June Lester has developed a simple tangram-type learning widget, accompanied by nine questions, to help students understand Pythagoras' theorem. Pythagorgrams require a Flash 6 plug-in. Lester, a mathematician at Simon Fraser University, started the Math Design site in October 2002, with her first article, "Math Design: the what and the why of it." She describes the site as a home for her ideas and demo experiments in designing onscreen mathematics, such as Pythagorgrams, focusing particularly on its visual and interactive aspects. http://thejuniverse.org/Mathdesign/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- BASKETMATH INTERACTIVE http://www.scienceacademy.com/BI/index.html Select a math topic from the list, then answer BasketMath's questions for feedback. Asnwer incorrectly, and it shows the correct answer; answer correctly, and it runs an animation of a basketball player shooting hoops. Each question is created randomly with variability. Topics include: - Addition - Subtraction - Multiplication - Division - Rounding Numbers - Writing Numbers - Order of Operations - Common Factor - Multiply Signed Numbers - Perimeter - Distance - Word Problems - Map Reading - Decimal Subtraction - Decimal Division - Adding Signed Numbers - Exponents - Bar Graphs - Verbal Reasoning I and II The "results" button presents a page listing the topics attempted, the number incorrect, and the raw score. This site is available in Spanish. http://www.scienceacademy.com/maestro/index.html -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- NRICH MATHS, THE ONLINE MATHS CLUB http://www.nrich.maths.org/ NRICH, an acronym for National Royal Institution Cambridge Homerton, is a collaboration between The Royal Institution, The University of Cambridge and Homerton College.
