Geometry+Collaboration+and+Sharing

===We encourage __everyone__ to share ideas and resources (lessons, tasks, 3-Acts, FALs, sample student work, websites, etc.) that you have created or found that may be helpful to Geometry teachers. Use the EDIT tab above to post resources. The discussion area at the bottom of the page can be used to discuss or inquire about posted resources, or to request resources from fellow Geometry teachers.===

Marbleslide Madness! (Standards for Mathematical Practice in action) - https://www.youtube.com/watch?v=gZ3eV6v9Ij8
Excellent video of Georgia students engaged in all of the SMPs. The students are part of an Algebra I class at North Hall Middle School in Hall County, Georgia. This video was part of [|Dan Meyer's blog post //Marbleslide Madness//]; a post which called attention to the new Desmos [|Marbleslide activity].

A few other sites which show the SMPs in action are: Inside Mathematics: Mathematical Practice Standards - http://www.insidemathematics.org/common-core-resources/mathematical-practice-standards Illustrative Mathematics: Practice Standards - https://www.illustrativemathematics.org/practice-standards Teaching Channel: Mathematics Videos - https://www.teachingchannel.org/videos?page=1&categories=subjects_math&load=1
