I teach a technology class to elementary school students, and it is so important that we begin the year learning the language of computers.
This is an extensive handout which covers all the vocabulary "basics" that students need to know. There are 96 terms included. Once they know these terms, class becomes easier for them to understand because we are all on the same page.
I run this off in a booklet form. The kids love having their own books!
You can talk your way through them as a series of lectures, or you can put your students in groups and assign them a section of the handout to research and prepare as a PowerPoint so they can teach their peers.
