In this project an elf will ask you what your first and last names are. Then using the first letter of each of your names, it will look up lists and put together what your elf name is.

The starter project that you will use has 3 lists already setup:

1. An alphabet list that has the 26 letters in the alphabet
2. A first names list that has 26 Christmassy first names
3. A last names list that has 26 Christmassy last names

When you tell the elf your first name, he will get the first letter of your name and get index number of it in the alphabet list.

For example if your name is David, he will get the letter D and then lookup in the alphabet list what the index number for D is, which is 3. Then he can get the number 3 item in the first names list which is 'Mistletoe'.

And then the elf will do the same thing using the first letter of your last name and the 'last names' list.

We've created a starter project that has the 3 lists already created. Open this starter project by clicking on the following link:

You can upload images and sprite files into your project. To upload a sprite follow these steps:

1. First save the image or sprite file onto your computer. You do this by right clicking on the image or link and then selecting 'Save image/link as...'.
2. Choose a location on your computer such as your desktop and save the file.
3. In your Scratch project, put your mouse over the Choose a Sprite button.
4. Click on the 'Upload Sprite' button.
5. Go to the folder you saved your file.
6. Select the file and click 'Open'.

The new sprite will upload into your project and appear in the stage area.

We need to create 2 variables:

• an index variable to store what index number of the items in the lists to use.
• an elf name variable to store what our elf name is.

Create the 2 variables and then add the following code to the elf sprite to start off the elf name variable as blank.

In the Variables palette, create a new variable by clicking the 'Make a Variable' button.

Once you click this button a box will appear asking what you want to call your variable. Give it a name that reminds you what you will be using it for. For example, if you wanted to keep track of your score in a game, you would create a variable called 'score'.
