### So each person gets  ' + '  +  0/8  + 1/16 + 1/32 + 0/64 + ' of a cookie

We can write each share as an infinite bimal: 0.110110' In a decimal the places are 1/10, 1/100, 1/1000,...whereas in a bimal the places instead are 1/2, 1/4, 1/8, ...

Try some cookie-sharing as Brad did, or cut into 3 equal pieces instead of 2, or 10  equal pieces; see what happens!

See "share any way you like" on the MAP, for other interesting cookie-sharing  that kids and adults have done .

Tim, a 50 yo M.D. was studying calculus with Don via IM, for his work. He was using Don's Worksheet book, and said, 'I was working my way through the cookie problem (Ch.2) and while using the scissors that can only cut into two pieces the binary system suddenly clicked and made sense to me for the first time. I could find the binary equivalent of 1/5 and other fractions'.

Kaitlin found 3 ways to write how she shared 3 cookies between 5 people

Sara, and Maya, 7 yo twins, find Patterns in division like 10/1, 10/2, 10/3, 'using cookie-sharing

Eva shares 5 cookies between 3 people!

A computer program to get bimals from the # cookies and # people, is in the answer section in ch. 2
