A member of the Problem of the Week staff since 1999, Terry created many Algebra Problem of the Week puzzles, and mentored thousands of students who participated in that and our other PoW services. We remember him for his passionate teaching and exploration of algebra and number theory. MY STORY, MI HISTORIA http://www.trottermath.net/mystory/ Read an episodic account of Terry's life, in his own words. \|/ THE WORLD OF TROTTER MATH http://www.trottermath.net/ The site includes a variety of math lessons, activities, and investigations from Terry's teaching experience. He organized them under the following topics: - Activities with Simple Operations - Number Theory & Primes - Math with Calculators - Activities Involving Recursive Operations - Problem Solving - Solve Trotter's Own Problems (STOP) Math - Digital Expressions - Pythagorean Theorem - Games in Elementary Math - Number Trivia - Basic Algebra - Humor or Items of Lighthearted Math \|/ ALL THE KING'S DIGITS http://mathforum.org/~terry/kings/ Challenge: Using each of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 once and only once, and the operations of +, -, x, Ö, sqrt (square root), cbrt (cube root), ^ (raise to a power), and ! (factorial), along with grouping symbols, write expressions for the counting number 100. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CYNTHIA LANIUS JOINS THE MATH FORUM STAFF After 12 years teaching high school mathematics, five years leading Rice University's Center for Excellence and Equity in Education as its Executive Director, and most recently serving as Technology Integration Specialist for the Sinton (Texas) Independent School District, Cynthia Lanius will join the Math Forum staff as Associate Director. Cynthia has worked with the Math Forum on several projects over the years. "I am a long-time admirer of the Math Forum and its fabulous staff," she says, "and am so excited to become a part of its future. I hope that I can support others the way that the Math Forum has supported me." Cynthia has published a web site since 1996 that features an extensive collection of her math lessons. About her site, she says, "When I first started publishing mathematics on the web, I fell in love with the medium. I had a vision that students would be playing on the computer and come across this math, and think, 'This is pretty cool.' I also wanted the site to be a resource for teachers, but I knew for teachers to use it, I had to tie it directly to the curriculum. Plus, I worked with university mathematics professors -- I knew the mathematics had to be precisely correct. I felt I had been successful when I heard from third graders and mathematics faculty alike saying they liked the site." In her position at Rice University, Cynthia helped to build the Center for Excellence and Equity in Education (CEEE) into a national organization. CEEE's mission is to promote greater participation of underrepresented groups in the sciences and to encourage academic excellence for all. Cynthia will bring this experience to her position here at the Math Forum. Cynthia and her husband, David, reside in the coastal bend of Texas. They enjoy travel, especially to visit their children and grandchildren in Indiana and Texas.
