Free Online "Thinking Tools" for the Classroom

I'm working my way through my Intel guide to using the Intel(R) Teach [Thinking With Technology] Program, and I'm being reminded of how many resources are made available free on the Web at http://www.intel.com/education . There's a Seeing Reason tool at www.intel.com/education/seeingreason, a Showing Evidence tool at www.intelcom/education/showingevidence, and a Visual Ranking tool at www.intel.com/education/visualranking. To use them with a class, you'll need to register in the teacher workspace area, so you can do behind-the-scenes setup of the scenario that will suit your class. There are a lot of project examples and unit plans offered for each tool, to guide one in thinking about how they could be adapted to an individual classroom.
