top number by the bottom number. Look at their table. 1/64 = 1 divided by
64 = 0.0156, right? To go from Decimal to Millimeter, *multiply* the
decimal number by 2.54 (why?). Example from their table: 0.0156 inches (")
times 2.54 = 0.3969 millimeters (mm). To go from millimeters to decimal inches,
*divide* the millimeter number by 64 (once again, why?). Example from
their table: 0.3969 millimeters divided by 2.54 = 0.0156 inches. Hint: There
are 2.54 millimeters = 1 foot (12"). How many *centimeters* =
1 foot?

Fraction
to Decimal and Millimeter Table from HamUniverse
"Convert fractions to decimals and millimeters and reverse." Nice!
It comes with good, clear instructions. To which we add these words of advice.
You can do most of this manually! To go from Fraction to Decimal, divide the
top number by the bottom number. Look at their table. 1/64 = 1 divided by
64 = 0.0156, right? To go from Decimal to Millimeter, *multiply* the
decimal number by 2.54 (why?). Example from their table: 0.0156 inches (")
times 2.54 = 0.3969 millimeters (mm). To go from millimeters to decimal inches,
*divide* the millimeter number by 64 (once again, why?). Example from
their table: 0.3969 millimeters divided by 2.54 = 0.0156 inches. Hint: There
are 2.54 millimeters = 1 foot (12"). How many *centimeters* =
1 foot?

GNUmber Munchers "is an educational math program based on MECC's early 80s munchers games, with new graphics." So writes Will Heublein, whose two fun and playable Number Munchers tributes are your freeware alternative to hunting down those old games and trying (usually without success) to make them run again. OK, so these are not exact clones of the MECC games, but they're close enough! We've been using them with elementary and middle school students for a few years now and they get the job done. No mouse needed, just use the arrow keys. GNUmber Munchers 2010 is an online beta version that runs fine on Internet Explorer. We wish more people would emulate Mr. Heublein and redo some of the good old MECC games! To download these games: Go to the very bottom of the GNUmber Munchers page where it says "Old Windows versions (Downloadable .exe files):" Standard version is for upper elementary/middle/jr high students, Elementary is for elementary kids. What is GNU?

of a ground-breaking mathematical physics theorem which bears her name (The
Chayes-McKellar-Winn Theorem)." So yeah, she's qualified. What we like
about this book, and all her math books for tween and teen girls is - she's
been there & done that - she explains things in a special girl-to-girl
BFF way, *without* dumbing down the math. Teen girls and co-eds use
this book and it really helps!
