This summer, by accident I developed the 'Proper Fractions' app. (Pr.Fr. Amazon)
I was developing a new version of the 'Equivalent Fractions' But the development has been stopped for unknown reasons.
This left on my hands a circle, a square and a number line of fractions, all of them interactive.
Surprisingly for me, it proved to be very useful for exploring in unit fractions.
One issue that concerned me since I developed "Old Egyptian Fractions" for Mathcats.
I decided to do some videos to show it. It is a collection in a YouTube Playlist:

The main videos in the list:
"Explore The Ahmes 2/p table of the Rhind Mathematical Papyrus":
Explore the Akhmim n/17 Table:
Proper Fractions It is a tool that can be useful in solving problems of Egyptian fractions:
Like the MathCats game:
