I first found this classroom resource from Jenna Wegner on Twitter.  Neave Interactive is a fun site that is a digital playground packed full of resources and student creativity programs. The creator of this site is Paul Neave, I encourage you to follow him on Twitter as well. Neave Interactive has some great game-based learning environments for students to use.  Not all of the Neave sites are educational but the ones below are some that I thought could be used in the classroom.  Just click on the images below to be linked to each site.  The first one, Bouncy Balls, is my teacher favorite because the balls will bounce according to the noise in the room.  This a great visual cue to the noise level in the classroom.
