Problem-Solving:
The 23 Skiddoo
Challenge
Today's
Snack: 23
whole peanuts, and sip a glass of milk in 23 sips.
--------------------
Supplies:
Scratch paper and
pencil
Using
numerals, symbols, graphics, words, pictures, or whatever you want, see how
many times you can express the meaning of the number "23."
Examples
to get you going:
•
(2 x 10) + 3
•
The first odd number after 22
•
The Earth's precise angle of tilt from the Sun in degrees.
How
many more can you list? (Hint: a sports star's jersey number . . . number of
yards you need to make when it's 3rd and 23 . . . 10 + 10 + 1 + 1 + 1
. . . something to do with chromosomes . . . see if you can get 23 of these!)
Don't
hesitate to ask someone older for more ideas. They may know, for example, that
23 is a "prime number." Ask them what that means!
By
the way, where does the expression "23 Skiddoo" come from?
No
one's exactly sure, but they think it means something like "everybody run
away," and dates back to pre-World War I American slang.
