  • You need the learning experience of Elementary Math.
  • You don’t need to be students in grades 8-9th.


In this course, you will master math concepts that are essential to solving math at the high school level. This course consists of five video lectures: mixed number and improper fractions, prime factorization, order of operations and other rules on calculation, and exponential expressions (parts 1&2). Each video describes math concepts in detail using handwriting, narrations, and captions. Visuals with narrations will be easy to follow the instructions. These concepts are instructed in middle school math. However, I often see my students have ambiguous knowledge of them.  In this course, I select topics with which my students tend to be confused. It is good for you to review those. Math videos include English and Spanish captions. Math terminology is a universal language. If you are comfortable learning math in your native language, first, learn in your language, then relearn in English. I recommend watching videos at your own pace. Once you understand basic math rules, it will become easier to solve math problems. Be aware that your math skills will improve when you get basic knowledge and have confidence in math.  The course will continue to grow. If you complete this course, you will receive information when the course expands.

Who this course is for:

  • People who wants to be comfortable with learning Math.
  • People who are struggling with Math.
  • People who want to review knowledge in Math.
  • People who want to learn with dual captions.

My name is Mari Hayashi. I have taught Math in the United States and Japan for several years. Math is like games. When you know the rules, you can go through them with your inspiration. If you think you are not good at Math, you just don't know the rules. I created Math videos based on my teaching experience.
