Students' learning is enhanced when they discover mathematical insights on their own in the spirit of becoming independent learners. We will introduce participants to some easily posed unsolved open problems in elementary number theory including the Collatz, Goldbach, and Home Prime conjectures. The use of the TI-89 CAS will aid in the discovery.
