Mathematics is the study of the measurement, properties, and relationships
of quantities and sets using numbers and symbols. It is also dazzling, magical,
perplexing, challenging, cool, awesome, and fun. Research has shown that the
more-abstract concepts become more concrete when modeled onscreen and guided
Center for Technology and Teacher Education: Mathematics
Teaching students how to think mathematically through hands-on technology
is one of the goals at the Center for Technology and Teacher Education. The
focus for this project was developing lessons around graphing calculators,
Geometer's Sketchpad, Microsoft Excel, the Explore Math.com Web site, Global
Positioning Systems, and MicroWorlds Logo. Activities range from Collecting
and Numerically Analyzing M&M Data to Exploring Geometric Constructions
of Parabolas. Files for completing the activities can be downloaded into your
Elementary students will love the Lemonade Stand. It's a great way to introduce
variables and business economics. The Tower of Hanoi is a game of skill and
logic in which rings must be moved from one pole to another in the proper order
by size. Dozens of other thinking games will keep students occupied for hours.
Count On is an awesome site that features games, puzzles, mysteries, and
competitions for all ages. In the game Dino Dig, students learn how to plot
the X and Y axes while looking for dinosaur bones. In Math Mysteries, students
can help Dottie Double fix the computer and tally votes at the Pop Awards.
For teachers, there is a database of problems to search and use in the classroom.
Educational Java Programs
WOW! These Java applets, complete with instructions and lesson plans, were

Does it make a difference where you shop? How could I send the check and
not pay the bill? Involve families in learning math by sending students home
with challenging problems. In these two examples, students interpret graphs,
compare prices, and examine probability. Students can move on to more difficult
problems, which help them to think about other possibilities. There are more
than 75 challenges available that are indexed by the title of the challenge
and math category. Figure This is a joint project of the National Council of
Teachers of Mathematics, the National Action Council for Minorities in Engineering,
and Widmeyer Communications, with support from the National Science Foundation,
and the U.S. Department of Education.
Fun Mathematics Lessons by Cynthia Lanius
Loads of lessons can be explored at this super site. Lanius has designed
practical, fun ways to teach math in the classroom. For instance, the unit
on fractals begins with, "Why study fractals?" Then, it continues with making
fractals and culminates by answering a series of questions based on the experience.
The Jurassic Park fractal is really cool to make. Some of the other lessons
are Stressed Out: Slope as Rate of Change, Mathematics of Cartography, Rectangle
Pattern Challenge, and Million Dollar Mission.
Widely viewed as one of the best search engines on the Web, Google has expanded
its features to include a calculator. Simply type in the calculation such as
sqrt(9) or 26/3, then press the enter key for the answer. The calculator
understands many different units, as well as many physical and mathematical
constants. Experiment with various weights and measures, including pounds,
cups, and kilometers. It won't replace the graphing calculator, but it is an
easy-to-use tool for checking calculations.
