## How do you select and sequence examples in math lesson?

In my previous post about examples, I described different uses of examples in teaching mathematics. In this post I’ll give a series of examples for us to be conscious about sequencing examples in our lesson. What are the things do you consider when you think of an example in a math lesson? And how do… Read More »

## FOIL Method is Distributive Law

The FOIL method is not that bad really for teaching multiplication of two binomials as long as it is derived from applying the distributive law or more officially known as the Distributive Property (over addition or subtraction). The FOIL method is a mnemonic for First term, Outer term, Inner Term, Last term. It means multiply… Read More »

## How to Teach the Equation of Linear Function

In my earlier post on Linear Function, I described how a linear function can be recognized based on equation, graphs, and tables. In this article, let us talk about how to derive the equation of linear function (as they are called in calculus) or the equation of a line (as they called in analytic geometry).… Read More »

## What is a Linear Function?

What is a linear function? In mathematics, a linear function is used to name two different but related notions. In calculus and analytic geometry, a linear function is a polynomial with a highest degree of one. In linear algebra, the linear function is the linear map. This article is about the linear function in calculus… Read More »
