  2. A man was out walking in the desert when a voice said to him, "Pick up some pebbles and put them in your pocket, and tomorrow you will be both happy and sad." The man obeyed. He stooped down and picked up a handful of pebbles and put them in his pocket. The next morning he reached into his pocket and found diamonds, sapphires, rubies and emeralds. And he was both happy and sad. Happy he had taken some - sad that he hadn't taken more.

  7. HOW TO SOLVE A PROBLEM Step I. Understand the Problem (Put Your Pencil Down) Collect Relevant Data Read the Question What You Have (Knowns) What You Want (Unknowns) Step II. Choose an Appropriate Strategy Act It Out Choose an Operation Draw a Picture Guess and Check Look for a Pattern Make a Chart or Table Make an Organized List Use Logical Reasoning Work Backwards Rafe Esquith Teach Like Your Hair is On Fire Step III. Solve The Problem (Pick Up Your Pencil) Step IV. Analyze Your Result Does My Answer Make Sense?

  10. Stoichiometry Pre-Supposes Balancing Equations, Chemical Reactions and Calculating Molar Mass Introducing Stoichiometry Utilize One Basic Balanced Equation Ammonia N2 + 3H2 ---> 2NH3 Rust 4Fe + 3O2 ---> 2Fe2O3 Simple Equation Varied Coefficients Work all Aspects B

  11. Synthesis A + B  AB Decomposition AB  A + B

  12. Single Replacement AB + CD  AD + B Double Replacement AB + CD  AD + CB
