A few summers ago I wrote a blog post about finding math in unexpected places as a way to keep skills sharp through the summer break. One of the unexpected places I talked about was the world of tabletop Role-Playing Games (RPGs) such as Dungeons & Dragons. Such games are essentially communal storytelling exercises which use chance elements to help guide the story via a set of polyhedral dice.
I've been running a D&D game for a group of friends for several months now, serving as “Game Master.” As Game Master I serve as lead storyteller for the group, while the others each create a character to experience the story firsthand. My job is to create the framework for the story. I devise and flesh out the world that the story takes place in, present challenges for the players to overcome, and rationalize the effect their actions have upon the world. Overall, my goal is to create circumstances that will allow the players to be heroes. Today I'd like to delve a little deeper...

We did it! With hard work, determination, my high school students passed their regents exams. I tutored US and Global History, Living Environment, Earth Science, Algebra Core, Algebra 2/Trigonometry, Geometry and Chemistry and the students passed. One student passed with a 70%, another 75%, 76% and another 79%. All the other students scored 80% and up.
I am so proud of my students. Well done students and parents, we did it!

Math Student's Civil Rights

Math is all around us. We use math to calculate the speed of the earth rotating about its axis. We use math to calculate the radius and height of a water tank to store enough water for a town. We use math to calculate the amount of carpeting material to purchase for our houses, and we use math to calculate the amount of fabric material to purchase to sew a pillowcase for our pillows. This means that you cannot run away from math. Even the dosage of painkiller medicine that your body needs depends on your weight and the use of math.
I have another example of the applications of math in our everyday lives. Movie theaters like any other for-profit business, have a budget with expenses and income columns. In order for the movie theater to break even, it needs to sell a minimum amount of tickets. This movie theater needs to sell a minimum of 100 tickets as the sum of the of tickets purchased. Also it needs to make a minimum of $100 from the sum of the tickets purchased in order to break...

Once upon a time, I was an engineer. And in that environment, engineers would think it was insane to depend on a calculation, a computer program, or a sketch - without checking the result, and if possible, checking it in the simplest way possible.
Fast forward to now. You have calculating power in your hand that was beyond what I could do with a long computer program when I first entered an engineering career. Your problem is, you depend on it. The teacher gives you a problem and what do you do? You reach for the calculator.
So look: the human brain is infinitely more powerful than the best calculator you can put in your hand. Learn to reach for it first instead. Use it to set up your work, to help you understand why you're doing it, to help you recall how you did what you did, and to find out what it takes to do things right. THEN grab the calculator. Otherwise, the thing the calculator does best is give you the wrong answer fast.
Nearly all...

We're going back to basics today with a Math Journey covering the three broad categories of symbols. I've found this concept very handy when introducing Algebra to middle school students. So let's go!
Math is a language, and I find it often helps to think of it as such right from the beginning. Just as there are different parts of speech in a language, so there are different 'parts of speech' in math. Where a spoken language includes parts of speech such as nouns, verbs, and adjectives, math has three major types of symbols: constants, operators, and variables. Let's go over each one in detail.
Constants
These would be the equivalent of your nouns. A Constant is a number – it has a single, discrete place on the number line. Even if the number itself is ugly – a non-terminating decimal, for example – it still does exist in a specific spot somewhere on the number line. In addition to the obvious constants, math frequently uses what I refer to as 'special constants'...

Growing up as a bright student who wanted to be cool meant that I stayed away from math subject like everyone else - then I got to Algebra. The ability to find the unknown through remembering formulas simply intrigued me and I learned as much as possible. As I went into High School and college, I found that the use of Algebraic equations could be a life saver if you simply needed to find the value of something upon demand. I used them for sales to get the best prices, for Excel because the macros are not as easily remembered, for budgeting money as an adult to assure I stay on target and any other time I need to find the answer quick. Once you learn the rules of Algebra, the rest is a piece of cake. I will make you a believer.

All my grade 8 & 9 students (10 students) passed the Algebra Core Regents exam. Only one student had to retake it in August and she passed with an 83%. In June she scored 53%. My two Trigonometry students passed the Regents, but only 2 out 4 students passed the Geometry Regents exams.

**If you wrote down the wrong step once, you must write down the correct step twice.**
Re-write the correct steps, start to finish, at least twice, at most 5 times start to finish.
That way, you will have recorded the incorrect method once, but you will have recorded the correct method twice. That will reinforce the right method more, so you don't accidentally memorize your mistake.
It's easy to teach yourself the wrong way to solve a problem if you don't correct your mistakes more often than you make them in the first place. Everybody learns visually (reading), verbally(hearing), and kinetically(writing), so if you wrote down the wrong ?? step once, you're one step closer to teaching yourself your mistake.
Do not review any mistakes by only looking at the answer given to you on the sheet. It won't sink in (without writing it down.) Like I always say, nobody likes studying, least of all me. ;) Correcting yourself in the short run will allow you to study less in...

Sure, we have all heard our math teachers say "Study for your test tomorrow." While we can all agree the importance of studying and getting prepared for an exam, not many math teachers actually tell you HOW to study. I am sure we have all spent time making flash cards, staring at our notes, or watching last minute videos on youtube, only to realize the test results often don't correlate to our effort. Before long, these upsetting experiences and test results created a scar in our minds, that statement we have all heard before: I am just not good at math.
The truth of the matter is, many people who have expressed their inability to understand and perform well on mathematics simply don't know how to study for a math exam. After all, those negative signs and multiple choice questions are often so tricky, even though you calculated every step correctly until the very end, all it took was one single mindless error that can well ruin the entire result. If we closely...

Physics students make up the lion's share of my current teaching efforts here at Wyzant. I've stuck mostly to AP and the first-year undergraduate level of physics, specifically in the non-calculus-based version of physics.
For non-calc physics, the mathematical skills required are surprisingly low. Since students at that level are rarely (if ever) asked to derive or define equations, the only math they need to succeed is the most basic form of algebra - we're talking about adding and subtracting variables from both sides of the equation! Without exception, every physics student I teach knows how to do at least that much. So why do they need our help?
My theory is that as a tutor, physics is best taught as a puzzle game. My students' classroom teachers provide the rules of the game at the beginning of every unit, and those rules are nothing more than the various equations and constants relating to whatever topic the students are learning at the time.

Greetings!
Are you preparing for the PSAT, SAT, & ACT quantitative exams?
So are we!
My name is Paul J. and currently I have 3 students in Vero Beach, Florida who are preparing for these exams this summer. We are looking for motivated students to join us for private lessons. A limit of 5 students has been placed, so there are only 2 positions available.
Lessons will cost $30 an hour, and we plan to do 2 one hour lessons a week for 5 weeks starting in early.
Our goal is to score well enough to compete for scholarships such as Bright Futures and the National Merit Scholarship.
If you are interested, please message me on my WyzAnt Profile.
Best regards!

There is some confusion among students about the distinction between "undefined" and "indeterminate". This article will give a couple examples of both, along with some explanation.
First, here's a generic example from algebra, where we solve an equation by finding the value of the variable.
2x + 4 = 12
The solution to this equation is the value of x that will make the equation true. We can simplify by subtracting 4 from both sides:
2x = 8
Then, divide both sides by 2:
x = 4
Placing 4 back into the original equation in place of x:
2(4) + 4 = 12
8 + 4 = 12
12 = 12
With that illustration in mind, let's look at an expression that is said to be undefined:
5/0
Rather than just saying "we can't divide by 0", let's see what happens when we turn this into an equation and try...

Settle in, folks, today's a long one.
In
The Function Machine, we learned that functions can be depicted as curves graphed on a coordinate plane. In
What Does the Function Look Like?, we learned how to tell the general shape of a function's graph based on characteristics of its equation, and vice versa. Today, we'll be focusing on linear equations (meaning any equation that graphs into a straight line).
The defining characteristic of a linear equation is that the highest power of x in the equation is x to the first. This denotes that for every y value, there is exactly one corresponding x value. Of course, there is always exactly one corresponding y value for every x, but this is one of those “square is a rectangle; rectangle is not necessarily a square” moments. We know there's exactly one y for every x because we choose our x's independently and the y's are dependent on them. There can't be more than one y for any given x; you've only got one output slot...

The primary student baseline communication skills a student should learn from their tutor are the following:
Precise use of vocabulary
Express complete thoughts
Asking questions
Interpreting and following instructions
These baseline communication skills are common in academia, particularly Mathematics. Any behaviors, thoughts, attitudes, philosophies, etc. that hinders these baseline communication skills presents learning hindrances for the students and tutors.
Let me know your thoughts.

Purpose: This series shares tips on how to identify, manage, and overcome Mathematics Negative Self Talk (NST). We cannot avoid NST totally because the NST about Math skills in general is a widely accepted habit.
So what is Mathematics NST anyway? Mathematics NST is when we speak in our minds or to others about an inability to learn, do, and/or understand Mathematics in general. Focus here is what we cannot do or have never done in Mathematics. For example, "I hate Math." "I can't do Math!" "This is too complicated!" " I could never do Math!" "My parents aren't good at Math either." "What can we use Algebra for anyway?" "The teacher is confusing me." The NST phrases list is endless, but also popular in today’s culture.
Downside of NST: NST in Math is simply a bad habit of thinking and attitude. This habit limits learning Math...

Reading Formulas can make or break how a student comprehends the formula when alone - outside the presence of the teacher, instructor, tutor, or parent.
Formula For Perimeter of Rectangle: P = 2l + 2w
How To Read: The Perimeter of a Rectangle is equal to two (2) times the Length of the longer side of the rectangle (L) plus two (2) times the Width of the shorter side of the rectangle (W).
When is reading formulas like this necessary? At three particular moments, reading this formula in this manner can be effective.
When students are initially learning what the formula means
When student are learning what it means when they should already know (remediation).
When students want to remind themselves (basics learning study skill habit)
Remember, Formulas at their introduction are complete statements or thoughts. Students cannot and will not recall complete thoughts or statements...

One of the first things you notice in algebraic expressions (besides the sometimes haphazard mix of operations) are numbers that appear with a smaller number above them (like this 54). These smaller numbers are called exponents and, in this post, I'll give a basic rundown of what they represent and a few basic rules that you will need to follow when dealing with them.
So, you're probably thinking, what do exponents represent anyway. In short, it's a special way of writing a special form of multiplication. I know it sounds hard to grasp, so I'll give you an example:
- Let's look a 3*3. Of course we know it as 9, but in dealing with the order of operations writing a number multiplied by itself may be combersome if you already have several parentheses in the expression. so the way that 3*3 would be written is 32
as your multiplying 3 by a second 3.
But what if you want to represent 4*4*4 or need to multiply 10 5's? Simply count up the...
