GCSE Mathematics MATHEMATICS CURRICULUM UNITS Yale-New Haven Teachers Institute (YNHTI) http://www.cis.yale.edu/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." http://www.cis.yale.edu/ynhti/curriculum/indexes/m.x.html#mathematics Statistics curriculum units range from "Paper Airplanes" to "Scaling the Natural World Using Dimensional Analysis." http://www.cis.yale.edu/ynhti/curriculum/indexes/s.x.html#statistics Search for units or guides from the YNHTI home page; a full list appears in the Directory of Volumes: http://www.cis.yale.edu/ynhti/curriculum/units/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CALCULATOR V1.0.1 - Harold Thimbleby, Tri-Bar Software http://www.tribar.dabsol.co.uk/calculator.html 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 factorial of?). 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. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- GCSE MATHEMATICS Philip Adams, GCSE Answers Limited, U.K. http://www.gcse.com/Maths/pre.htm Exam preparation materials, including: Basic tutorials with Java - negative numbers - probability - 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.
