### Tangrams Sample Projects

This year, I am going to try to be good about scanning in stuff that my kids have made, so you can see how a project is intended to look / work. :) I love it when other teachers post pictures or videos of what goes on inside the classroom. It makes their lessons seem so much more real!

Here is one. The tangrams project was super fun, for both me and the kids. In the process, we learned how to find angles using adjacent angles in a diagram, how to find angles inside an isosceles angle, how to use Pythagorean Theorem to find diagonal lengths, how to find lengths of sides that "stick out" in a picture, and how to combine / simplify square roots and whole numbers! Wow. So much math in 2 or so days of class time. :) :) And the kids loved the puzzly parts of the project, piecing the tangram pieces together to make the silhouettes. Some kids also took the initiative to create their own designs and to find additional perimeters, which was really fun for me to grade!

Here are the scanned images of a couple of example projects. They look lovely in person, but the math work is in pencil (and some of the colors are also light), so the scanner unfortunately doesn't pick it up all too well. If you zoom in, you can see the math that they wrote next to the diagrams.
