Need an online, collaborative math idea for your kindergarten students? Here is a post for primary school teachers (mostly K) from the Class Blogmeister List Serve:
I am looking for teachers to add to a Math Trail wiki for kindergarten students. Each month a new problem will be posted that can be investigated in your school, playground, or surrounding neighborhood. Teachers will lead the investigation with their students and add their data to the wiki. At the end of the month teachers can go to the wiki with their students to make comparisons and conclusions about the problem of the month. Email me with your questions or ideas for future investigations.
This is the link to the Wiki
She already has the first math problem posted. Expect more great things to show up on this wiki!
