Dear Numeracy, Yes, Math journals are all *MY* idea (NOT)....One of my math mentors, the late Sue Stetzer, gave me a book called WRITING FOR MATHMETICS by a teacher at Germantown Friends school , Joan Ploughman (?) not totally sure of her name. We have had extensive discussions on Numeracy of math journals and I'm a big fan of them. Perhaps as I came from a literacy background I still want the written word as part of my student/teacher communication?

Well, only "3" new students showed up yesterday... this class has tragic attendance problems... and 2 of them had "bad days" of not understanding "ANY" math.. but, I asked the entire class to answer : What is the process you use when you shop and want to estimate or "round" the prices? My two new "fragiles" got panicky so in an effort to "help" (and totally mess up my chance of a more student generated answer) I said, "What would you round an item that cost $7.89 to? an item that cost $ .39? I read the responses and got the predictable $8.00 from everyone... and $ .40 from all but 2 of the 12 in class. They said $ .50... I think this will work better in the future if I do it when we are learning estimation, maybe before we do any "formal" estimating? It may take me a while to collect some meanigful data on this? Take care, Lynne
