Spend 10 minutes writing about it mathematically.  Your writing can be in note form or in the form of calculations.  Think about all the topics we have studied in this unit.  You can look in your Prime Time or in your math journal to help you get ideas.  Consider writing about some of these topics:

  1. Prime
  2. Square
  3. Even/Odd
  4. Divisibility rules
  5. Factors
  6. Multiples
  7. Factor Pairs
  8. Factor Rainbow
  9. Factorization
  10. Prime Factorization
  11. GCF
  12. LCM

Use this applet to find the number of moves (M) it would take for any number of discs (D).

Write one page describing your strategy and how it connects to the formula.  Use diagrams if you need them.  Your writing should be proofread and all diagrams must be made neatly.
