One of the many sites now creating real world Math lesson plans. This site is the best Ive come across, and each lesson comes with an accompanying student handout and sliderocket presentation complete with video and associated student notes.
This is a great book mark that shows all the properties of numbers and some valuable equations. It would be great for students at the abstract level with these concepts who just need a quick reminder. Simply print the book mark, cut it out, and hand out!
