Zoom - Concepts and Properties of Numbers (IV.1.HS.2)
Outstanding!
This site starts with a picture of a square meter
and "zooms" you out by powers of ten
to get a sense of what the base ten system represents.
- Benchmark 3. "Develop an understanding of
the properties of the real and complex number systems
and of the properties of special numbers including
?, i, e, and conjugates."
- Buffon's
Needle - Concepts and Properties of Numbers (IV.1.HS.3)
Buffon's Needle is one of the oldest problems
in the field of geometrical probability. It was
first stated in 1777. It involves dropping a needle
on a lined sheet of paper and determining the
probability of the needle crossing one of the
lines on the page. The remarkable result is that
the probability is directly related to the value
of pi.
