Polygon Fractions  Measurement Tour  Geometry Bibliography
NO MATTER WHAT SHAPE YOUR FRACTIONS ARE IN by Cynthia Lanius
http://math.rice.edu/~lanius/Patterns/
A new unit for grades 36 that uses hexagon, trapezoid, rhombus, and triangle shapes to explore geometric models of fractions and discover relations among them. These Web pages connect math, art, writing, technology, arithmetic, and geometry.
Topics cover:
 identifying fractional values  equivalent fractions  adding and subtracting fractions  ordering fractions  identifying geometric figures and their properties
Lessons are arranged so that students can work independently or with guidance from the teacher, and should be printed so children can draw and color the appropriate shapes.

A TOUR OF MEASUREMENT
http://forum.swarthmore.edu/paths/measurement/
This is the second in a series of 'tours' planned by the Math Forum to help teachers find classroom materials for specific subjects. It is arranged by topic and level and includes lesson plans, questions and answers from the Dr. Math archives, software suggestions, and resources for students.
The page structure of this unit follows that of our earlier Tour of Fractions:

_MATHEMATICS TEACHER_ GEOMETRY BIBLIOGRAPHY
http://forum.swarthmore.edu/mathed/mtbib/
Recently updated to include a listing of geometry articles published through 1996, this bibliography compiled by Hubert Ludwig, Professor of Mathematics at Ball State University, has been hosted by the Math Forum since our previous incarnation as the Geometry Forum.
The bibliography is divided into 38 subcategories; topics include answers to questions like "How/Why Should Geometry Be Taught?" and popular subjects such as the Four Color Problem, Tessellations, and Higher Dimensions.
