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

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

"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.)"
