Prior to this lesson the students learn about the various ports and cables that are visible on a computer. They use this information to help them to identify computer hardware.
Students examine 12 computer parts (I use old parts form junked computers) that have been labeled 1 through 12. They would with a partner or a small group to make an educated guess about what the part is and what it likely does.
Students are guided to create a spread sheet using Excel to record the predictions. Tye learn Merge and Center, Grid Lines, Bold Print, centering within a cell, and the terms row and column.
I usually project the document for the students to see as I go over each step. To easily access the links and have the directions at the children's fingertips, I also open the document on each screen and minimize it until I have introduced the lesson.
