Explaining Pythagoreans Theorem with Clay-animation

Using clay-animation is a creative way to teach students mathematics concepts, such as the Pythagorean theorem. For example, the Pythagorean theorem is a relation in Euclidean geometry among the three sides of a right triangle.

The theorem can be written as:


Note the demonstration shows how the two blocks start out with equal area (comprised of red triangles and blue squares). Taking away the 4 red triangles from each side of the equation, results in one large blue box (equal to C squared) and on the right side of the equation there are two blocks (A squared plus B squared). By manipulating the blocks, students can better understand how this physical relationship can be true. Enjoy!

  1. Wow, I wish someone had shown me something like that in math class when I was in high school.

  2. You all did an awesome job on the video. I know the theorem from lectures but seeing it visually like this really helps make sense of it!

  3. This is great! I think that it would be cool if the students made something like this.
