Secret Number

Today in math we learned how to "read minds" using this Secret Number game.  Here's how it works.

1. Have someone think of a number and hold it in their head (don't tell!)
2. Take that number and multiply it by two (add it to itself)
3. Take the new number and add 10
4. Take the new number and divide it by two (cut it in half)
5. Subtract your ORIGINAL number
6. Their answer should be 5!
