Google Drawings

I played around a bit with the tangram lesson by downloading the image from the link within the lesson plan and arranging the shapes some.
The software is almost the same as Educreations or some other white board. The two biggest difference is some added features and the fact that Educreations and other whiteboards usually have video record feature. The way I understand Graham when he discusses how Google Drawings play into CCSS Anchor Standard 1 is that it allows the kids to demonstrate their thinking and practice critical thinking and showing their thought process. This will then allow them to better write because they will be able to organize their thoughts much like an outline.
While playing with Google Drawings, I feel that for myself it would be difficult to integrate Google Drawings for such reasons. The controls are too complex and I feel students might spend more time trying to figure out how to work the software before they would actually be able to use it effectively. However, I do understand that some kids needs something more than a simple sentence outline. On the other hand, I feel that teaching Google Drawings might take more time than necessary to implement effectively.
The controls are very straightforward except for the fact that you have to use the "backspace" to delete objects instead of the "delete" button. There are tons of colors, shapes, and sizes to make the possibilities nearly endless. However, it is the sheer volume of these options that I feel would make it difficult for students to use to organize their thoughts through the creation of images and so forth.
