Generating Algebraic Expressions: Counting Hexagons

In solving generalization problems that involve figures and diagrams, I have always found working with the figures—constructing and deconstructing them—to generate the formula more interesting than working with the sequence of numbers directly that is, making a table of values and apply some technique to find the formula. Here’s a sample problem involving counting hexagons….

Equations, Equations, Equations

Students deal with a different ‘types’ of equations: equations in one unknown, equations in two unknowns, and the equation representations of function. There are others like the parametric equations but let’s talk about the first three I just enumerated. Is there a connection among all these three apart from being equations? Let’s take for example…
