NO MATTER WHAT SHAPE YOUR FRACTIONS ARE IN
by Cynthia Lanius
http://math.rice.edu/~lanius/Patterns/
A new unit for grades 3-6 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://mathforum.org/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://mathforum.org/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.
