Part 1: A numerical way of discovering the formula for x^2 - y^2.

Part 2: A geometric way of discovering the formula for x^2 - y^2.

Part 3: Pedagogical thoughts on the importance of students discovering the formula for x^3 - y^3.

Part 4: A geometric way of discovering the formula for x^3 - y^3.

Part 5: Guiding students to the formula for x^n - y^n.
