Welcome!
Open or CloseThis section provides you with FREE video selftutorials in the area of Basic Mathematics, also known as PreAlgebra. I start out explaining all about numbers, basic arithmetic, order of operations, fractions and more. Be aware that the tutoring is designed for students from Seventh Grade through College. It is NOT for those in Kindergarten through Sixth Grade.
Watching all these videos is a great way to prepare for Algebra!
Newer releases are at the bottom of this page.
*Special Note to Teachers, Parents and Tutors: If you plan to use my videos for teaching/tutoring purposes, you need to buy the DVDs (not just watch the free videos on this page with your students). The good news is no additional school licenses are needed!
Students: Although not required, it is appreciated if you could buy at least one DVD lesson from me. If you cannot do this, then perhaps you can make a small donation to my YouTube Channel.
Your purchases/tips allow me to dedicate more time to creating even MORE and BETTER videos for you! Thank you in advance!
NOTE: Most videos have associated PDF Math Notes or Worksheets. Visit my Printshop for details.

This lesson consists of giving you the necessary "preliminaries" to do fractions. The tutor explains what are factors, divisors, prime and composite numbers, how to do prime factorization, GCFs, LCMs, multiples, and the rules of divisibility. He also explains how to use your graphing calculator to help you find the GCF, LCM and multiples. 
Sieve of Eratosthenes
Open or CloseBasic Math: Sieve of Eratosthenes
This lesson consists of showing you how to use the Sieve of Eratosthenes to find all prime numbers below a certain value. In this case, below 100. 
Introduction to Fractions
Open or CloseBasic Math: Lesson 6  Introduction to Fractions
An informal introduction to why we need to learn about fractions.
The next 12 videos provide you with a SelfTutorial on fractions. This video series is different from the previous ones in that the use of printed Notes is integrated with the Video (Math Notes for other lessons may be used independently of the videos). This series is VERY detailed and covers the necessary areas to help students review the many aspects of fractions and fraction conversions. I also show you how to perform all the many different fraction operations and conversions using the TI84+ Graphing Calculator.
