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.

"Using Usenet for cheating by asking the exam question will
generally leave a fairly indelible trace. I'm curious to hear
from Danish educators; the article indicates that they've
allowed this since 2008. Has cheating via Usenet newsgroups
been a big problem for your exams since then?"

"I often get the following two questions from my
non-mathematician friends. Q1: Why is 1 not a prime? Q2: For
a, b positive integers (say), why is (-a)(-b) = ab? I could
answer as follows (but with not exactly good success): Answer
to Q1: If 1 is considered (defined) as a prime, then the
fundamental theorem of arithmetic is not true; and we
mathematicians do not like that! Answer to Q2: If not, the
distributive law is not true, and we mathematicians do not like
that either! Do we have any better answers for our
laymen friends?"
