Just posted 2 videos on Equal Fractions: The Missing Link

    The videos are for free download. The first video questions the mathematical reasoning behind the practice of multiplying the numerator and denominator with the same number to produce equal fractions. It also demonstrates that the reasoning behind the "multiplying by same number" rule contradicts the conceptual definition of Multiplication.

    The second video demonstrates the correct reasoning behind the actual operation needed to produce equal fractions. (Of course, it is assumed that everyone knows that equal fractions always represent the same (equal) quantities. If not, the video does carry a reminder).

    Both videos are without any voice-overs. No spoken words are used. Not one. Just flowing music. The argument is conducted using 4 types of reasoning that are the defining features of ALL Karismath videos: (a) Visual (explicit) (b) Verbal (implicit) (c) Numerical (explicit) and (d) pedagogical (explicit and implicit.). The conceptual underpinnings are unraveled entirely visually, using animation.

    The videos are well-suited for teacher training as also for self-learning. Hope you enjoy them. (The music is not so bad!)

    I assume the clue is in the title: The Missing Link.

    I had to google the site, Karismath, mentioned in the post, go there, click on a link for one of the videos there to get to his youtube channel, and then go to the home page for his channel to find the videos in question.
