I thought that process isn't correct but now i know that its effective

They are too "manly" to color! HA! Too funny. And typical! I can imagine that guys who would say that.

Like Soul, I really like the video, plan to favorite it. I plan to use it in my classes and see if my students can pick out the same thing about perimeter that Soul noticed was overlooked about the diagonal lengths.

Nice video.

In your section on perimeter, however, you seem to count the lines that cut diagonally across a square (e.g. 7, 11, 13, 14) as one unit. Unfortunately, the length of the diagonal of a square is greater that it's sides. The length of the diagonal is "side x the square root of 2".
