During this engaging and interactive digital lesson, the learners will receive direct instruction and practice using a scanner for images or objects, saving a scanned image as a file, identifying components such as the scanning surface and scanning beam, and understanding how a scanner works.

Scanning a picture is only the first step. After a digital image is in the computer and saved as a file, students can perform various tasks involving the image. For instance, they can insert the image into a document, use graphics software to change or enhance the image, add the image to a Web page, and so forth.
Students can scan text in addition to pictures, but if they want the text to be editable letters and words instead of a picture of the words, they would need to use a special type of program called Optical Character Recognition (OCR) or document imaging software.
Before students take the lesson, show the classroom's or computer lab's scanner to students. Point out the scanning surface, cover, scan head, and lamp. Also note that the scanner is a peripheral device.
In this lesson, the examples use music notation. Therefore, you might want to tell students about the treble clef, bass clef, and notes, particularly quarter notes. Consider drawing the clefs and a quarter note on the board so students will recognize the symbols.
