11 November 1996 Vol. 1, No. 6 Fractals Lesson | Math Line Puzzles | Why Learn Math? THE MATH FORUM INTERNET NEWS http://mathforum.org/ FEATURED INTERNET RESOURCE: FORUM NOVEMBER HOT SPOT http://mathforum.org/~steve/steve/current.html FRACTALS LESSON by CYNTHIA LANIUS http://math.rice.edu:80/~lanius/frac/ This lesson plan is designed for elementary and middle school students. Written to comply with suggestions in the NCTM Standards, it uses fractal geometry to introduce students to modern mathematics and to connect arithmetic and geometry. The lesson also connects math with art, writing, history, and career information. Students learn how to make a fractal by constructing two famous examples: the Sierpinski Triangle and the Koch Snowflake. Math questions and challenges follow activities; "What's so hot about fractals?" explores why fractals are fun and useful to study. Finally, links to other fractals on the Web and where to learn more about them are included. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- From the Forum collection of K-12 Math Tips and Tricks: LINE PUZZLES http://mathforum.org/k12/k12puzzles/ Can you connect the dots in a 3x3 grid using 4 straight lines? Can you plant 7 rosebushes so that they form 6 straight lines with 3 bushes in each line? How about 10 bushes in 5 lines of 4 each, or 19 bushes in 9 lines of 5 each? If you find these puzzles easy, try constructing nine triangles by drawing three straight lines through a capital M. .::. .::. .::.

Three Math and Education students at the University of Richmond (Jen Peck, Karen Rosser, and Carol Pifer) have put together a clever series of Web pages called "What Good is Math?" So You're Planning a Trip? Art and Math: How Could They Be Related? Will I Ever Be Able to Fill My Piggy Bank? How Did I Get a C in Spanish? So You're Planning a Party? http://www.urich.edu/~ed344/math/mathhome.html .::. .::. .::. There are other interesting questions like yours to be asked. Why should the public support mathematics? What do mathematicians do that is important? The Math Forum has collected some answers, and we'd like to hear from you.
