This course is designed for teachers, math coaches, and/or
curriculum developers who are interested in the Math Forum's

***TI-POW INDEX PAGE
http://mathforum.org/tpow/ti.pow.html

These five tPoWs, freely accessible and modeled on the Math
Forum's Problems of the Week, take advantage of TI-Nspire
technology. Students are invited to use the link "Submit your
answer" to share their solutions, and then "self-mentor"
using specially designed hints and checks.
