could work
if i had a jelly bean for every book. perhaps?
Because if I tried to weigh all my books it would take forever (got 7508 of them)
and Im not counting pages, plus, they are of all different sizes and values.
I had tokens for every 7 books the children read for pizza. I put them in a big jar, and looks like its full. I need to count them to see how many books they read last year, and then ask them to guess, but maybe a smart kid will weigh the jar, divide the amount by 7 and get at the number of tokens in jar.
