Powers of Ten SUZANNE'S INTERACTIVE LESSONS - Suzanne Alejandre "Middle School Mathematics Curriculum," a position paper written for the 1998 NCTM Standards 2000 and Technology Conference, outlines an approach to teaching mathematics that integrates activities, exercises, manipulatives, and technology: Lessons showing the way Suzanne uses this approach in the classroom open with Student Pages; a link at the top of each page leads to a Teacher Lesson Plan. - Traffic Jam (Hop, Skip, Jump) - Locker Problem (a thousand lockers) - Bricks (build a wall without fault lines) - Dominoes (polyominoes) For a table of contents of SUZANNE'S MATH LESSONS, see: -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- JOHN AND BETTY'S JOURNEY INTO COMPLEX NUMBERS - Matt Bower Now hosted by the Math Forum, this children's book-on-the-Web from Australia is designed to introduce complex numbers in story form in a way that is intuitive and enjoyable for students. John, Betty, and their dog Trevor solve a series of problems designed to introduce topics such as: - integers - fractions - surds - imaginary numbers - complex numbers - Argand diagram - vectors - multiplication in polar form - relating polar and Cartesian form - De Moivre's theorem - Mandelbrot set To order the book in hard copy, you may use the form provided on the Web. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- POWERS OF TEN - Bruce Bryson A visual journey from quarks to quasars: images based on the book _Powers of Ten_, by Philip and Phyllis Morrison and the Office of Charles and Ray Eames. Each picture's subject is ten times wider or narrower than the next. Images range from quarks at 10^-16 meters to groups of galaxies at 10^25 meters, with related information about objects of each size and Java animations of the images.
