Python Modules for Cryptography and Number
Theory with M. Culler

Right now you have to talk with me
if you'd like to use these modules. They are designed to be used
in teaching number theory, cryptography and/or python programming.

Real Analysis Activites for
Teachers with MST students

This will come when I get to it.

Number Theory for Teachers

This is an interactive book for use in teaching Number
Theory with applications to cryptography and teaching algebra. If
you would like to have the original word documents to modify for
your own use be in touch with me.

Workshop
Geometry, 2010 with J. Sallee

This interactive workbook for teaching geometry to future
elementary and middle school teachers is the current text for MATH
141. If you'd like to download and print this file make sure that
your pdf reader does not scale before printing.

Workbook Calculus for Middle Grade
Teachers

This is a list of many probems designed to help future
elementary and middle school teachers explore the ideas of
calculus. Rather eccentric and overly ambitious in its scope, there are none-the-less
some interesting problems, some making connection to middle grade
mathemtics, as well as more traditional practice problems. Includes
references to Hughes-Hallett, Edition 3, and an early edition of
Hungerford's Precalculus. Much is review of concepts
learned in MATH 140 and MATH 141, the required sequence of mathematics
courses for future elementary teachers.
