TOOLS FOR UNDERSTANDING
John Woodward; University of Puget Sound
http://www.ups.edu/community/tofu/
A resource guide for extending mathematical understanding
in secondary schools, for educators who teach mathematics
and are interested in integrating common technologies into
their daily instruction. Most of the lessons on this site
were piloted, revised, and re-piloted in middle-school
classrooms over a three-year period.
Onsite strands include MATH CONCEPTS, with lessons on
fractions, geometry, functions, and other common
pre-algebra topics; and INTEGRATED LESSONS that combine
technology with written communication, providing examples
of in-depth problem-solving in mathematics.

Lessons incorporate spreadsheets or describe how to use
calculators, word processors, and presentation software
as part of a problem-solving process or as a tool for
completing a project. There is also an entire JOURNALING
strand on mathematical writing and how to use math journals
- simple paper and pencil "technologies" - as a complement
to daily instruction.

SIGNIFICANT FIGURES AND ROUNDING RULES - Christopher Mulliss
http://www.angelfire.com/oh/cmulliss/
A detailed investigation of the "rounding rule" - Where did
it come from? How often does it fail? How can it fail?
Is there a better alternative? This site supports the
teaching of significant figures and rounding rules in high
school and college science courses.
Included are links to related sites, and a detailed study,
"On the Standard Rounding Rule for Multiplication and
Division," by Christopher Mulliss and Wei Lee.

LEARNING STRATEGIES DATABASE
http://www.muskingum.edu/~cal/database/Database.html
Background information, the purposes and advantages of
various learning strategies, and descriptions of specific
strategies, from the Center For Advancement Of Learning at
Muskingum College, New Concord, Ohio.
Several general-purpose strategies are suggested, together
with recommendations for math: how to use substitution for
solving problems involving fractions and variables, and for
word problems; and memory strategies for learning terms and
definitions, symbols, equations and rules, and problem
solutions (the correct order of steps required to solve
math problems successfully).
