 Welcome. Do you like a challenge? Do you like to solve puzzles with either numbers or language? Are you interested in Leonardo Da Vinci and the Renaissance? If you answered yes to these quetions then you will really enjoy this project.
 To take part in the Crack the Code section you need the password. To get the password you must prove yourself worthy! You must complete the Patterns and Codes sections where you will receive the password. Half the password is given when you complete the Patterns section and the second half of the password when you finish the Codes section.
 Two heads are better than one! Certainly when it comes to cracking the Da Vinci Code  work with a partner and discuss each of the puzzles. Good luck.
Patterns  What are they?
 If you want to solve the Da Vinci Code, you need to know about patterns and codes. Patterns are all around us. Some of these patterns show interesting number sequences  that is the way numbers follow on from each other. You can sometimes find a rule in a sequence by looking at the difference between the numbers. Sometimes it takes more careful examination of the pattern to see what the sequence is. What is the next number in this pattern: 1, 2, 4, 7, 11, ? (Answer at the bottom of this page).
Codes  What are they?
 "What are codes?" you ask. Codes are really secret messages that you use to send private messages. "How do you solve a code?" you might ask. Well, you have to have a keen eye, and you need to think about them. Codes are easy to solve, if you know how to write one! Let us look at number patterns first and then we will look at different codes. To write a code is easy. Here is an example of a code: aTbHcIdSeIfSgAhCiOjDkEl. The one I wrote was just the abc's but every second letter is a letter of the message; mine says: THIS IS A CODE. If you know how to write a code then you can certainly read one! You've just got to use your brain!
 What is the next number in this pattern: 1, 2, 4, 7, 11, ? The answer is 16. You got that! I knew you would  it was easy wasn't it? The rule is to add a number that is one bigger each time, so you add 1, then you add 2, then you add 3, then you add 4 and last you add 5. So 11 + 5 = 16.
