Common Sense offers great reviews and advice to parents as well as educators. Their new Beta site - Learning with Technology - reviews apps, games, and other media for kids in terms of learning.
This free app provides instant access to the Common Core Standards. Not sure what to do with it, but it could be useful from an administrative/lesson planning stand point.
This free version combines electronic and paper assessment for quick grading. Teachers can access pre-loaded Common Core standards and create unlimited answer sheets.
This app could be a great review for a basic physics class. It includes a study guide and covers most common units such as motion, vectors, energy, and optics.
"CCL4s provides an interface for entering observation data as well as access to all the Content Standards for Mathematics K-12 and the ISTE NETS.S. The collected observation data can be shared via email or with our unique built-in instant meeting. The graphs are very interactive and allow observers to merge different observations to compare and contrast different teachers or the same teacher over time. Using the Timeline feature, observers can track the observed Look-fors through time."
