100TH DAY OF SCHOOL

http://mathforum.org/t2t/faq/faq.100.html

In the coming weeks, many students will be attending school for
the 100th day this school year.

The 100th Day can be a lot of fun -- and a teachable moment!
Counting up to 100 for the 100th day of school gives teachers
many special opportunities to investigate place value.

The discussions and links to Web resources found in the FAQ
provide many ideas to make your 100th Day a memorable
experience for your students.

Now taking place: math education conversation of the day

"While on his death bed, the brilliant Indian mathematician
Srinivasa Ramanujan cryptically wrote down functions he said
came to him in dreams. Now 100 years later, researchers say
they've proved he was right. 'We've solved the problems from
his last mysterious letters. For people who work in this area
of math, the problem has been open for 90 years,' Emory
University mathematician Ken Ono said."

AT RIGHT ANGLES

http://azimpremjiuniversity.edu.in/registration-form-download-math-magazine-issue-2

Enter a name and address to freely download the 8Mb December
issue of At Right Angles, which features pedagogy and
technology articles on

- how to approach problem solving in geometry
- using a spreadsheet to explore the Monty Hall problem
- the role of open-ended questioning in
classroom teaching
- the axiomatic basis of origami, and an unexpected
construction possible under the rules of paper folding
- pitfalls in the teaching of the method of induction
- exploring constructivism

This Indian publication's second issue came out during the
country's "national year of mathematics" and the 125th birthday
of Ramanujan. The article entitled "A math connect across the
centuries" claims that Ramanujan likely discovered an algebraic
identity that led him to a result in Euclidean geometry -- a
topic that rarely appears in his notebooks.

The inaugural edition of At Right Angles introduced math
portfolios, math clubs, and a visual way to teach the birthday
paradox. Download the June issue and other joint publications
of the Azim Premji University from

Now taking place: math education conversation of the day

"A simple math puzzle: This year, 2013, all the digits of the
year are different. When was the last time we had a year like
this? (It's been a while. For our students -- and even for
some teachers -- this is the first year in their lifetimes that
a year has had all digits different.)"
