What is a TI-Technology PoW?
TI-Technology Problems of the Week (TI-PoWs) are freely accessible problem-solving challenges modeled on the Math Forum's Problems of the Week that take advantage of the TI-Nspire™. Students are invited to use the link "Submit your answer" to share their solutions, and then "self-mentor" using specially designed hints, checks, and suggestions for extensions.
