MATHEMATICS CURRICULUM UNITS
Yale-New Haven Teachers Institute (YNHTI)
An educational partnership between Yale University and the
New Haven Public Schools, designed to strengthen teaching
and learning in local schools.
Produced by teachers participating in Institute seminars
since 1978, over a hundred volumes of teaching units offer
ideas and procedures for teaching English, history, social
studies, languages, the arts, mathematics, and science in
elementary, middle, and high schools. Each unit includes a
guide with a synopsis and recommendations, an introduction,
lesson plans or sample problems, and a bibliography.
Mathematics curriculum units range from "Integrating
Mathematical Concepts in the Study of the Atmosphere" and
"A Chronological History of Pi with Developmental Activities
in Problem Solving" to "Practicing Precision: Lessons from
Mathematical Language and Writing."
Statistics curriculum units range from "Paper Airplanes" to
"Scaling the Natural World Using Dimensional Analysis."

CALCULATOR V1.0.1 - Harold Thimbleby, Tri-Bar Software
A freeware Macintosh calculator that balances equations for
you as you type them in. Its functions include the usual
four arithmetic functions, as well as exponentiation,
trigonometry, logarithms, and factorial. Many functions have
options that support generalizations: multiplication, for
example, can also be used for finding roots or prime factors;
and division can find rational approximations. All functions
have inverses, even factorial (what is 40340 nearly the
The calculator includes a list of numerical constants and
formulas, such as the radius of the earth and all SI prefixes.
Requires System 7.1 or greater.

Exam preparation materials, including:
Basic tutorials with Java
- negative numbers
- trigonometry 1 (right-angled triangles)
- trigonometry 2 (sine and cosine rules)
"Easy Starts" followed by "Heavy Duty Stuff" for reviewing
algebra, functions and sequences, graphs, probability,
ratios and fractions, 2D shapes, 3D shapes, and trigonometry.
Students are advised to work through the questions, work out
the answers on paper, and compare their solutions with
answers on the site.
GCSE Mathematics forms part of the GCSE Answers site, which
also offers English tutorials and handy tips, and English
and English literature syllabi.
