MathPickle advocates the establishment of a set of thirteen
$1,000,000 unsolved problems — one for each grade
K-12 — with the prize money to be split between the person
who solves the problem and their most inspirational K-12
teacher. The final selection of these thirteen problems, and a
discussion of the merits of the million dollar prize money,
will take place in Banff (Canada) this November:

"As the student solutions below show, there was some variation
both in the expressions and in how you made the comparison.
Finally, while we don't generally feature solutions that did
not use algebra, I'm including Andrew's here because it's kind

"That may be true, but there is also truth in the converse:
passionate mathematicians, those with strong
platonic/aesthetic inclinations, often have a hard time in
current academia. For one thing, there are no 'generalists'
anymore. There is no place for such a concept today."

Report of the 2012 National Survey of
Science and Mathematics Education
A report came out last week about a survey that garnered the
participation of 7,752 science and mathematics teachers in
schools across the United States.
The Report of the 2012 National Survey of Science and
Mathematics Education (NSSME) — the fifth in a series dating
back to 1977 — provides up-to-date information and identifies
trends in the areas of teacher background and experience,
curriculum and instruction, and the availability and use of
Data tables include
Prevalence of Block Scheduling
Factors Seen as Inhibiting Effective Instruction in the
Randomly Selected Mathematics Class, by Grade Range
Mathematics Classes in Which Teachers Report Using Various
Activities at Least Once a Week, by Grade Range
Amount of Homework Assigned in Classes per Week, by
Subject and Grade Range
Characterizing the percentage of schools offering school-based
programs to enhance interest and achievement in math as
"strikingly low," this NSSME also finds that
at a time when only 62% of the K-12 student enrollment is
White and non-Hispanic, roughly 90% of mathematics
teachers characterize themselves that way
mathematics teachers tend to feel less well prepared for
finding out what students thought or already knew about
the key ideas to be addressed in a unit, and anticipating
what students might find difficult in it
43% of elementary mathematics classes use the Internet
weekly, compared to just 26% of middle school mathematics
classes and 11% of high school mathematics classes
the two factors seen as most serious problems for
mathematics instruction are low student interest in the
subject and low student reading abilities
