Math Awareness Month
http://www.mathaware.org/
The American Mathematical Society, the American Statistical
Association, the Mathematical Association of America, and the
Society for Industrial and Applied Mathematics announce that
the theme for Mathematics Awareness Month, April 2010, is
Mathematics and Sports.

Capturing Teacher Knowledge Study
https://teknoclips.org/
The federally funded Capturing Teacher Knowledge (TeKno)
project at the University of Arizona invites teachers to
participate in a study designed to analyze how teachers think
about ratio and proportions.
Participants are asked to:
 Fill out a background information online survey
 Take an online mathematics survey on ratio and proportion
 View and comment on 12 clips from math classrooms on ratio
and proportion topics
 (Optional) Administer a student assessment on ratio and
proportions twice, once as a pretest and again as a
posttest, before and after you teach ratio and proportions
(instructions and copies are online)
For those teachers completing the task, the TeKno project will
provide a $75 Amazon.com gift certificate. Participants
collecting pre and posttest data will receive an additional
$50 gift certificate.

Complex Numbers
http://whyslopes.com/complex.html
Since we last featured the fractions section of Alan Selby's
site "Appetizers and Lessons for Mathematics and Reason" in
January this year, he has revised and expanded the section on
complex numbers, organizing it under these topics:
 Addition and Multiplication [of vectors]
 What Are Complex Numbers?
 Addition and Multiplication Properties
 Second Way to Compute Products
 Consequences of Two Ways to Compute Products
These pages provide a way to introduce complex numbers before
the study of periodic (unitcircle based) trigonometric
functions.

calculus topics, see:
