### A Challenging Way of Presenting Math Patterns Problems

Mathematics is the science of patterns. Part of the math skill students need to learn in mathematics is to see regularities.  The usual way of introducing pattern searching activity is by showing a sequence of figures or numbers and then asking the students to find or draw the next one.   Here’s a more exciting…

### 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…
