# Christmas Pixel Puzzles: Free Color by Number Activity

These Christmas Pixel Puzzles are a great way to introduce image representation on computers as well as work on number and color recognition.

Computers break pictures down into tiny blocks of color known as pixels. Pixels are organized in a grid and each block contains a single color. When you combine the pixels, they create pictures.

The more pixels there are, the higher the resolution the picture has. High-resolution pictures are more detailed and appear smoother than low-resolution pictures.

A pixel is a unit of a digital image, typically a tiny square that has a single color. Pixel is short for picture element.

These Christmas Pixel Pictures have a resolution of 625 pixels (25X25) and 225 pixels (15X15). Each square on the grid has a number that indicates the color that should be colored in that square. Look up the colors using the key.

## Program Your Christmas Pixel Pictures

Think about the different ways you can complete your pixel pictures. You can color all of the squares in one row before moving to the next or you could color all of the squares of one color before moving on to another color.

You could work in a section and branch out from a square until you have to move on to another uncolored square. Another fun way to complete your pictures would be to work with a partner and a plain piece of graph paper.

Read the numbers to your partner and have them color the squares as you go.

## How Do Computers Store Images?

Computers take images and convert each pixel into a number that is stored with a corresponding string of numbers. In computers, the numbers used are all 0’s and 1’s called binary code.

Careers that work with digital images include graphic designers who design images for marketing, advertising, product packaging, and more.
