I saw on Twitter that one of my peeps was told that this year they will develop their own /Professional/Personal Learning Network. Just in case that happens here, this may help get someone started.
Mathwire.com is designed to provide activities and appropriate worksheets for teachers to use in their classrooms. All activities and worksheets support the constructivist approach to learning mathematics and the NCTM Standards.
I think placing a survey or poll on your classroom blog or website is a great way to get informal feedback from your students. I usually put a survey on my class blog a week or so before any formal assessment that my students are going to take. That feedback helps me identify the areas that my students need more help and or clarification on. - R M Byrne
