Thanks for stopping by my Web of video math tutorials!
These skills are important
- virtually all 2 and 4 year degrees have math requirements that include
some algebra.
But it's not just about the classes you may have to
take. Being able to work with variables, letters that stand for
numbers, is important. That is what algebra is. Being able
to confidently and accurately work with variables means we are ready to
apply math to real-world problems.
This means we can:
- Work with equations and formulas
- Solve for missing variables
- Build mathematical models that describe or predict
- Understand probabilities and statistics
- Prepare for successful careers in science, engineering,
medicine, and management, and business
Math Minutes are short videos, 5-7 minutes, about
fundamental skills that prepare us for success in math and algebra
classes. We think you will agree, getting started isn't hard.
Our goal is to give you choices - different ways to review and learn.
The concept was created by Mr. Breitsprecher and some
high school math teachers. We saw a need for multimedia that
allowed students to use multimedia and visual presentations to help them
learn. Our videos are not meant to replace text books, classroom
instruction, or study sessions.
We do know from experience, that all students we work
with can be successful in math and algebra classes if they get support
when they needed. Our online webcasts of Math Minutes are
available 24/7 to preview and review whenever is needed.
Students can benefit from these video tutorials in 3 ways:
-
They can be used to preview new materials so that
students have a class of looking at new concepts before class.
-
They provide alternative presentations that can help
students feel more comfortable and confident practicing skills and
successfully completing homework.
-
They provide a starting point to talk, allowing students
to visualize and review as needed so that they feel more comfortable
talking to teachers, classmates, and tutors about any additional help
they may need.
CLUB TNT, on My Madison TV14, will feature some of our
Math Minutes episodes during the 2009/10 season, but they will always be
online here anytime you need a quick review. We will add print
resources to support each video early next year and launch a podcast
series too.
Please scroll down our list of topics and take a look.
If you have any questions, comments, or ideas to share, we would love to
hear from you - please email us at

Study Tips & Tricks. Getting a "crisp"
start in a math or algebra class is the best way to ensure you are
comfortable and successful. Math is very different than other
subjects taught in school, let's talk about how to excel in class this
year.
-
Definitions & Symbols. In many ways, math
is like learning a new language. There will be new words and
symbols. Let's review what you need to get started.
-
Divisibility Rules. Recognizing when a number is
divisible by 2, 3, 4, 5, 6, 7, 8, 9, and 10 without a calculator is
important -- it prepares us to work with fractions, common denominators,
lowest common multiples, and factoring. There are patterns in numbers.
-
Factoring Prime Time. In many ways, algebra
is all about taking numbers and expressions apart and then putting them
back together in simpler forms. Multiplication tells us that 2*3=6.
Factor is the reverse -- 2 factors of 9 are 2 and 3.
-
Decimals. Being comfortable with decimals
and understanding what they represent makes working with numbers easier.
Perhaps more important, when we can comfortably and accurately work with
them, we are ready to master related math skills.
-
Fractions, Decimals, & Percents. We can make some decimal numbers
easier to work with by converting them to percents - per one-hundreds.
That is actually what "percents" are.
-
Percentages: Tipping. Many service
providers need to earn some of their wages from the extra money
customers leave when they are satisfied with services. This is a
great "real-world" example of how we can apply our understanding of
decimals and percents.
-
Fractions 101.
Working with fractions is an important part of many classes -- it is
also the foundation of many algebraic concepts. Here are the basics.
-
Simplifying Fractions. They key to working
with anything is to learn ways to make things as easy and manageable as
possible. Keep It Simple Students, the
KISS principal applies here. Let's review how to keep fractions
simple to work with.
-
Fractions: Common Denominators. Being
able to compare fractions means being able to apply what we know about
simplifying fractions and creating equivalent fractions. With
practice, its easy!
-
Fractions: Addition & Subtraction. If we
understand common denominators and simplifying fractions, with practice,
we will quickly and accurately add and subtract them.
-
Fractions: Multiplication & Division.
Just like using whole numbers to calculate surface areas, perimeters,
and other useful formulas often demands we multiply and divide numbers,
to use fractions in useful ways, we must be confident in our ability to
multiply and divide.
-
Properties of Real Numbers. Here is a review of
different types of number sets, properties of real numbers
-
Negative Numbers, Part 1. Positive integers are all the whole numbers greater than
zero: 1, 2, 3, 4, 5, ... . Negative integers are all the opposites of
these whole numbers: -1, -2, -3, -4, -5, … But let's take a few
minutes to look at this in more detail and how we add and subtract
negative numbers.
-
Negative Numbers, Part 2.
Let’s review a little more about negative numbers. We’ve covered the basics and
how to add and subtract positive and negative numbers. Now, let’s look at
multiplication and division.
-
Simplifying Expressions. An algebraic expression is a mathematical
phrase which contains numbers, operators, (such as add, subtract, multiply, and
divide), and at least one variable (like x, or y). Expressions have no equals
sign. To work with expressions, we need to agree on the order we use to perform
operations.
-
Linear Equations in 1 Variable. A variable is a number that is not
identified. It is often represented by "x" or "y," any letter can be used.
A linear expression is a mathematical statement that includes addition,
subtraction, multiplication, and division, but has no exponents (or powers) and
no variables that multiply or divide each other.
