Word problems not your thing? Panic strikes when you come across yet another word problem? Starting your first year at teaching Sixth Grade Math and you're stuck on ratios? This blog will explore the secrets of breaking down word problems.

We are going to focus mostly on 6th grade level word problems involving fractions, ratios, rates, percentages, and some Common Core solution concepts including Tape Diagrams, Double Lines, and other related graphical analysis techniques. I may also explore other math-related territories as the mood strikes me, so let me know if you want to focus on some other aspect or grade level of word problems.

HOW TO USE THIS BLOG: The Blog Posts show up as the most recent ones at the top. However, I would recommend you start with the oldest Posts first and work your way to the most recent as some of the posts build on previous ones. But hey, you're the Teach...so whatever works.

The links on the side of the Blog will connect you to whatever Post you want to work on.

I hope you learn a little, and enjoy it in the process...and feel free to ask questions or offer suggestions/criticisms.

6. A Few Words About Nothin (i.e. Zero)

In a previous post, we dabbled a bit in ratios.  However, I failed to mention at that time that the denominator, the number below the line, the second number of a ratio, shan't be a Zero. Many word problems dealing with ratios may provide a word problem having a ratio of a/b and then quickly add where b is not equal to zero.


The reason is this:  you cannot divide a number by Zero.  It's not allowed, it's against the law of mathematics, I'm sure it violates some federal law and maybe even the Constitution, and besides, it just ain't fittin.  Only terrorists divide by zero.

If you find yourself faced with a ratio or fraction type problem where the denominator is zero...STOP!   Put down your pencil.  And call the authorities immediately.
