One thing that is happening in the creation of my own web page/blog site (whatever we are going to call this!), is that I am starting to imagine the Math Notebooks that students kept last year in addition to participating in a weekly blog question, might be better to create and develop into a more electronic format, and ownership of each student's own website or blogsite. So, these questions look good.
The second article is on Math in the News (summary and response sheet here), and offers oodles more ideas for topics, curriculum enhancement and relationship to economics and real world charts, graphs, usage of numbers and just the universality of mathematics.
